The Sibling Bond
Kittens who grow up together form a strong bond during the early weeks of their lives as siblings. This bond can lead to either a lifelong friendship or indifference between cats from the same litter. Much depends on factors like environment and age of separation. Kittens separated too early may fail to properly socialize, while those kept together too long risk developing litter mate syndrome. With the right approach, many sibling pairs can become happy, well-adjusted cats whether raised together or apart. This article explores the pros and cons of keeping cat siblings together and provides tips for raising litter mates successfully.
Pros of Keeping Siblings Together
Keeping sibling cats together from the same litter provides numerous benefits for their wellbeing. Most importantly, the familiar companion of their sibling helps reduce stress levels, especially during new or uncertain situations like adoption, vet visits, or moving homes (Basepaws). Kittens who stay with their littermates exhibit less distress behaviors such as vocalizing, hiding, aggression, or avoidance. The presence of their sibling promotes feelings of security.
In addition, kittens housed together show healthier immune system functioning and can model social skills from each other. Kittens raised with a sibling are often friendlier and better socialized around other pets and people later in life. The companionship between siblings also leads to more play, exercise and positive engagement.
Cons of Separating Siblings
One of the biggest cons of separating sibling cats is increased anxiety when they are apart. Cats can form deep bonds with their littermates that continue into adulthood. Separating cats who have been together since birth can cause them stress and emotional distress.
According to one Reddit user who split up their sibling cats after 2 years together, “Separating two bonded cats is cruel, and could have devastating consequences. The cat may fall into a depression that can cause health problems” (source).
The emotional toll of separation can be too much for some cats to handle. They may stop eating, become withdrawn, or engage in destructive behaviors. It’s important to consider your cats’ close sibling bond before deciding to separate them.
Litter Mate Syndrome
Litter mate syndrome refers to behavioral issues that can develop when siblings from the same litter are raised together without proper socialization. According to this article, litter mate syndrome happens when two cats from the same litter become overly dependent on one another for comfort and play, failing to properly socialize with humans or other animals. This over-attachment can lead to issues like anxiety, aggression, and stress when the pair is separated.
Litter mate syndrome is not a scientifically defined condition, but rather a commonly observed behavioral pattern. The main signs, as described by this source, include poor social skills with other pets or people, separation anxiety, fearfulness, and an inability to self-soothe. Siblings may resort to aggression or destructive behaviors when separated from their bonded sibling. While concerning, litter mate syndrome does not mean siblings need permanent separation. With proper socialization and training, cats can develop healthy independence while maintaining their sibling bond.
Bonding Outside the Litter
While cats from the same litter often form strong bonds as kittens, it is certainly possible for unrelated cats to form close bonds as well. Here are some tips for helping cats bond even if they are not from the same litter:
Introduce cats slowly and properly. Go through the proper introduction process over multiple days/weeks, keeping cats separated at first and slowly allowing supervised interactions. This allows them to get used to each other’s presence and scents before directly interacting.
Encourage positive associations. Give cats treats or play with toys when they are calm and content around each other so they associate the other cat with good things.
Ensure both cats have their own resources. Provide multiple food bowls, water bowls, litter boxes, scratching posts, perches, and beds so there is no competition over resources. This can reduce tension between cats.
Consider using synthetic pheromones like Feliway to help reduce stress and tension during the introduction process. Pheromones can help reassure cats and make them feel more comfortable around each other.
Be patient and go at the cats’ pace. Some cats may bond right away, while others may take weeks or months to become comfortable companions. Let them set the pace and don’t force interactions.
Give them positive one-on-one time with you as well. Spend one-on-one playtime, petting, and cuddle sessions with each cat so they don’t have to compete for your attention and know they are equally loved.
With time, patience, and positive reinforcement, unrelated cats can become the best of friends!
Ideal Age for Separation
Most experts recommend waiting until kittens are around 10-12 weeks old before separating them from their mother and siblings for proper social and emotional development. Kittens learn many important behaviors and skills from their mother and siblings during the first 8-12 weeks of life that prepare them for independence.
According to BC Humane, kittens should stay with their mom until at least 10 weeks old. During this time, the mother teaches them proper eating habits, litter box use, grooming, and social skills. Siblings also play together during this time which aids in development. Separating too early can result in issues like inappropriate elimination outside the litter box, poor grooming habits, and undersocialization.
Similarly, according to veterinary experts on JustAnswer, waiting until around 12 weeks of age is ideal before separating littermates. Kittens learn behavioral cues, boundaries, and social maturity from interactions with their siblings. Allowing them to stay together longer prevents issues like anxiety from sudden separation.
While 12 weeks is optimal, most experts say 10-11 weeks is sufficient for separation to adoptive homes or new owners. The key is ensuring kittens have adequate time to learn from their mother and siblings before being separated.
Signs of Unhealthy Bonding
It’s important to watch for signs of unhealthy attachment between sibling cats, as this can lead to anxiety and behavior problems if allowed to develop. Some key signs of unhealthy bonding include:
Clinginess – Siblings who are constantly attached at the hip and cannot bear to be apart even for short periods likely have an unhealthy bond. Healthy bonding means cats can be independent but choose to spend time together out of enjoyment. Constant clinging and neediness is a red flag.
Lack of independence – Sibling cats who rely entirely on each other for security and comfort, and show extreme distress when separated, lack a healthy sense of independence. Properly bonded siblings will be fine on their own for periods of time.
Aggression – Hostility toward other pets or humans in order to “protect” their bonded sibling relationship is a problematic sign. Healthy bonds do not require this possessiveness.
Excessive grooming – While normal social grooming is expected, constant and obsessive grooming between siblings can signify an unhealthy fixation.
Failure to thrive when apart – If siblings refuse to eat, sleep, play or function normally when separated, even briefly, it suggests an extreme interdependency.
By watching for clinginess, lack of independence, aggression, obsessive grooming and inability to thrive individually, you can spot unhealthy bonds between siblings and take steps to encourage healthy social development.
Tips for Raising Siblings
It’s important to provide adequate individual attention when raising sibling cats together. Each cat has its own personality and needs. Make time to play with each cat separately every day. Have individual bonding and training sessions. Give them separate sleeping areas. Feed them in different rooms or areas. This allows them to develop their own routines and prevents competition over resources. Reward good behavior in each cat individually as well. Giving cats their own identity and independence helps prevent litter mate syndrome. According to one source, “Rewarding one cat for good behavior is always an ideal strategy to encourage others in the pack to follow the rewarded one.” [1]
When to Reunite
In some cases, reuniting separated sibling cats can help foster connections between them and provide companionship. As social creatures, cats often benefit from having feline friends. However, the success of reuniting separated siblings depends on several factors.
Kittens that are separated early, within the first couple months of life, typically reconnect well when reunited as adults. According to one viral video, two cats that were separated as kittens remained bonded when reunited after a year apart. Kittens that are raised together establish close ties that can persist even after long separations.
However, cats separated later in life may struggle to reconnect. Siblings that have established independence and territory may see each other as strangers or competitors when reunited. In fact, one Redditor reported that their cats became hostile when reunited after 6 months apart. Reintroductions should be gradual in these cases, with scent swapping and separated spaces at first.
Overall, reuniting kittens or younger cats is ideal for maintaining bonds. But adult cats can also reconnect through slow and proper reintroductions. The companionship of a feline sibling can enrich a cat’s life, so reunions are worth attempting with care and patience.
Making the Best Decision
When deciding whether to separate sibling cats, there are several factors to consider in order to determine what is best for their well-being:
Age – Kittens under 6 months old may become too dependent on each other if not separated early enough. Older cats who have lived together for years will likely experience more stress if separated. The ideal age is often between 6-18 months for separation. (Source)
Bond Strength – Observe how attached the siblings are to each other. Do they spend all their time together or are they independent? Strongly bonded pairs will have a harder time being separated. (Source)
Temperament – Consider each cat’s individual personality and temperament. Confident, outgoing cats may adapt easier to separation than shy, anxious ones. Make sure separation won’t cause either cat undue stress.
Circumstances – If life circumstances necessitate separating siblings, do so gradually over time with positive reinforcements. Never separate abruptly. (Source)
Monitor closely afterwards for any signs of anxiety or undesirable behaviors. Be prepared to reunite siblings if separation proves too difficult. The well-being of each cat should guide the decision.
