How to safely separate brother and sister kittens before neutering?

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!

Thank you for submitting your question regarding your kittens. Yes, I would pick up their dry food late the night before surgery to allow them a short fasting period. Be sure to provide plenty of water though. It will be a good idea to keep them separate after surgery so they can rest. They will rebound quickly, but they do not need for their bodies to heal. Playing with each other could delay that from happening. I hope this information helps!

Cats can behave like this after any separation (even just as short as a trip to the vet). Generally this behavior will calm down. For now, separate food, water and litter box so that there is not competition. Also try a pheromone diffuser in the house to see if this helps to calm them down. Separate them if things become too aggressive and then reintroduce once they have calmed down. Best of luck with Lucy.

You really need to keep them separated - I agree 100%. I would put mom and kittens in the kennel but you need to make sure that mom has access to a litter box and her food/water and as the kittens get a bit older she will need to be able to get up and walk away from them at times during the day or they will drive her nuts. So, she cannot be in there until the kittens are weaned. I would say only for a week or two (maybe up to three). I don't know what the situation is, if you bred the cats on purpose or if they got pregnant by accident or what but please keep in mind that if you don't have the appropriate facilities for cats to be queening then you should get them spayed. This situation of trying to keep them separated is going to cause you a major headache. Also, keep in mind that will come back into heat sometimes almost immediately after queening so they can get pregnant again if there is a male cat in the house that has access to them or if they get outside. My other recommendation would be to get a Feliway diffuser to put in the room with them. It may help reduce stress: https://www.chewy.com/comfort-zone-feliway-cat-diffuser-48/dp/48072 Hope this helps. Best wishes!

Do not separate them. let them figure it out themselves. Cats will have tiffs no matter how much they like each other. The fact that they are grooming each other and lie with each other is a good sign that they like each other. Think of their tiffs as brothers having sibling tiffs. It is normal. Let them have their once a day fights. This will eventually subside.

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.

I would keep them completely separated for now to stop the behavior. Keep them separated for the next week, then slowly start letting them have time together. If the behavior starts again, immediately separate them again and try re-introduction in a few days.
