How to help my cat who became timid and scared after neutering?

It takes 4-6weeks after neutering before the hormones and related behavior subsides. Be aware however that not all bad behavior is hormonal and some cats will never be friends and many need to be segregated. Calming diets and supplements such as kalm aid can help alongside the feliway

The pet calming collar may be a good idea. I like the Sentry calming collar. I'd also get a Feliway diffuser. That releases calming pheromones when plugged in. Have them both seen by a vet for a wellness check.

You should have him checked, or rechecked, by your veterinarian. Neutering typically does not result in more aggressive behavior. Additionally, any sudden behavioral change can be due to illness or injury. Once medical causes have been ruled out, you can focus on behavioral issues. Consider a pheromone product, such as Feliway Spray or plug in diffusers, to help decrease anxiety or aggression. Provide additional litterboxes, bowls, toys and bedding to prevent resource protection. You may have to separate them for a week or two then gradually reintroduce them while employing the measures described above.

Hi, it is difficult for a semi feral cat to accept to be confined in a cage. It is probably easier to have a large room or just stay indoors where he feels he has control over his territory and resources. I would give him more space and the possibility of hide while making sure he does not lick/groom the surgery area.

It can take several weeks for testosterone levels to decrease after neutering. Until then, consider using a pheromone product, such as Feliway spray or plug in diffuser, to decrease any anxiety or aggression in the home. Provide extra litter boxes, bowls, toys and bedding to prevent food aggression or resource protection.

Thanks for using Petco Pet Education Center, formerly Petcoach! Cats, like people, have different personalities; some are very sociable and always want to cuddle, while others can be more reserved and independent. It may be partly personality contributing to his behavior, as well as adjusting to his new environment. A pheromone collar (they can be found on amazon, such as nurturecalm) may be a good option instead of feliway spray, as it is a continuous release for a full month. While the response is variable among cats, it is definitely something I would recommend giving a try. Additionally, if there is a type of treat that Vin really enjoys, I would recommend putting some down by you when you are sitting on the couch watching TV, etc. When he comes to eat them, don't force an interaction, but allow him to nibble on them and then decide where he wants to go. Over time, they can be moved closer and closer to you to encourage him to be more comfortable in close proximity. When he seems playful, play with him with a toy, etc and then allow him to leave when he is done. If he is on a feeding schedule, get his attention by opening a can or shaking food into his bowl, allow him to stand next to you and have a short interaction before you set it down. If he still seems uncomfortable after these suggestions, I would recommend either setting up a consult or reaching out to your regular veterinarian for further advice. Good luck!

They may always be enemies but there are a few things you can try to help calm them. I would start by putting some feliway diffusers throughout the house. They have a multicat version now. Feliway is a feline pheromone which is helpful to calm cats. It doesn't work on all. You could also consider putting some essential oils throughout the house. Be sure to get ones that are safe for cats. Visit oilyvet.com for more information. Also, make sure you have at least 3 litterboxes throughout the house, if possible, to prevent competition. If all this fails, you could talk to your vet about putting one (the instigator) or both on an antianxiety medicine to help calm them. I hope this helps!
