When a kitten is adopted alone, will they get lonely or more prone to unwanted behaviors? They say that there’s this thing called “single kitten syndrome”, which describes the behavioral issues that can arise when a kitten grows up without littermates or feline friends, missing out on important social lessons. But what gives? Is the single kitten syndrome a myth or is there some truth to it?
While there’s a lack of studies about it, it is apparent to many animal welfare groups that single kitten syndrome is real. In fact, it may sometimes impact how successful an adoption is. So if you’re thinking about adopting a feline friend or two, it helps to get to know more about kitten behavior and the single cat syndrome to know what to expect.

What Is Single Kitten Syndrome
Is single kitten syndrome real? Though not a clinically recognized condition, “single kitten syndrome” or “Tarzan Syndrome” is a concern among many behaviorists, especially when kittens under 12 weeks are adopted without a peer to help teach them healthy feline behavior. For instance, If a kitten plays too rough and causes pain, the sibling may yelp, and their mother is likely to step in to teach the kitten that such behavior isn’t okay.
There’s a reason why some rescue organizations strongly recommend or require adopting kittens in pairs rather than alone. In this video, Abby Engel, Director of Pet Angel Adoption & Rescue, shares that single kitten syndrome is the reason why they do not adopt kittens out as single cats - they have to be adopted out as a bonded pair if they’re under the age of one.
This is because kittens raised without littermates miss vital social lessons, like bite inhibition and appropriate play - skills they normally learn through sibling feedback and guidance from their mother. In short, if a kitten is adopted alone, they might lack social lessons learned through play and bonding, as well as healthy boundaries, and are more likely to develop behavioral issues listed below.

Recognizing Single Kitten Syndrome Symptoms
Single Kitten Syndrome can lead to behavioral challenges, especially in kittens raised without littermates. While not every solo kitten will experience issues, some may struggle with socialization. Common signs include:
- Biting or clawing during play
- Scratching or chewing household items or furniture
- Litter box - peeing or pooing outside the litter box
- Excessive clinginess or vocalizing
- Biting ankles as you walk
- Suckling on fabrics, people, or other pets
- Constant attention-seeking
In a Reddit thread under r/CatAdvice, a Redditor who works at a shelter shares that some single kittens grow up fine, while others need lots of extra play and attention to thrive. To prevent behavioral issues, her advice is to consider adopting two kittens instead of one, or a single older cat. And if you choose to adopt a single kitten,you should be ready for high energy and extra work.
The behaviors of kittens with single kitten syndrome can overwhelm new adopters, sometimes leading to returns. If your kitten shows these signs, it’s best to consult a veterinarian or seek advice from rescue organizations. Remember that each kitten has distinct needs, so caring for them should be tailored to their needs.
How to Fix Single Kitten Syndrome
If you're raising a solo kitten, consider adopting a second, because when kittens are concerned, two can actually be easier than one. They keep each other entertained, reducing stress and behavioral issues. If that’s not an option, here are some tips on how to socialize your kitten and help them thrive:
- Play daily with wand toys to avoid hand-biting
- Redirect rough play to toys
- Use puzzle feeders for stimulation
- Set boundaries: walk away if biting occurs
- Create safe, cozy resting spots
- Start litter training early with gentle guidance
- Ensure all family members follow the same behavior rules
Talk with rescue organizations to help you find the right solutions to help both you and your kitten. Having a reliable pet camera such as the Petcube Cam 360 can also go a long way in monitoring your kitten as he/she gets to know the world.
Conclusion
Single Kitten Syndrome might not be an official diagnosis, but the behavioral challenges it brings are very real for many solo-raised kittens. While not every kitten will develop issues, understanding their unique social and emotional needs is key. Whether you choose to adopt one kitten or two, early socialization, enrichment, and consistent care make all the difference. Instead of labeling behaviors, focus on your kitten’s individual journey. With understanding, patience, the right support, and a little extra playtime, any kitten can grow into a happy, well-adjusted cat.
