My cat attacks my new kitten and won't let me touch him. Help!

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 9 years and 2 months old | 10 lbs

My cat Jude has been more aggressive lately. He is eating and drinking fine and has lots of energy. I figured this could be due to me getting a kitten(Bunny) last October, because at the time Jude was not very happy about it. Everything seemed fine for like a month or two between them but now he is always attacking Bunny and won’t let me touch him. He has a good relationship with the other person I’m living with just not me. Please give me advice? What am I doing wrong? How do I support my cats?

Thanks for using Petco Pet Education Center, formerly Petcoach. This is not an uncommon story so don’t feel bad! Usually this stems from underlying anxiety- probably starting with getting the new kitten. Below are some tips that have been shown to reduce stress for cats and may help settle things down at your home. If these are not helping after a month or so, consider talking to your vet about anti-anxiety medication which can make a world of difference. -Feliway- calming cat pheromone- comes in many forms from pet stores or online. - Adding a litter box. Studies show that the ideal number of litter boxes for a home is #of cats +1 . This is regardless of how clean you keep his current litter box. - making sure she has plenty of “high space”. The safest (and therefore least anxiety-inducing) place for a cat is up. If you don’t have one (or two) already, get a cat tree or put up a shelf or two that she can go perch on. Best of luck to you and the kitties!
