Why is my unneutered cat suddenly mean to my husband, not his friend?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | unneutered | 1 year and 1 month old | 13 lbs

Hi my husband got a cat like one year before and it’s left paw was smashed by a vehicle. So he took him to vet and the vet said it should be cut off from that point to avoid the infection. So he did the best. And the cat grew up and my husband loved him a lot. Now he’s grown in to a big cat. The cat was with my husband and his friend who shared the room and that was before I married him. Recently cat has changed his behavior and furious towards my husband but not to his friend.

Cats can have very complex behavior and many things can cause stress or anxiety which can alter this behavior. If he is not neutered yet, this can also contribute to Poos’ stress. I recommend to have him neutered as this may help significantly. Otherwise many things can cause stress such as a change in the living environment, work schedule or being able to see other cats outside. Things you can do to help relieve stress in general are to set up a 30 minute play sessions for vigorous exercise and providing a climbing area such as cat shelves or a tall cat tree. There is a food called Calm made by Royal Canin which can help and a Feliway diffuser may also be beneficial. You will likely need to institute several of these methods. If he seems to be in distress or uncomfortable, have Poos examined by the veterinarian for a urinary tract infection or other causes of illness. There are also medications available that can help cats to deal with stress. Best of luck and please feel free to post any additional questions.
