My cat is hissing at her spayed sister. How can I ease their stress?

This can happen after a stay at the veterinary clinic. It should pass in a few days as Stella loses the scent of the clinic. You can try a pheromone product, such as Feliway spray or plug in diffuser, to decrease any anxiety.

Thank you for submitting your question regarding your cats. I suspect that Stella is stressed by the return of her housemate. Callie likely smells and acts a bit different after being gone for so long. I would keep them separate to allow them time to readjust to each other. They should get along fine, but it will take some time. I hope this information helps!

Hello, sorry to hear about Zelda. She may still be exhibiting some pain and discomfort from the surgery as it has only been a day since then. I would keep Zelda quiet and comfortable for at least 2 weeks while she recovers from her spay surgery. This kind of surgery is a big procedures that involves going deep into the abdomen to remove the ovaries and uterus. After the two weeks, if she is still acting very hostile then you may need to reset the introduction. Your other cat may also smell differently since she was at the clinic which may be causing Zelda to feel unsure. Again, giving both of them some time to recover from this surgery is likely your best option right now. You can give them both, nice comfortable bedding to sleep on and offer them plenty of quiet time so that they can rest. Keep them from jumping, running, or excessive rough play as this can lead to premature failure of the surgery site. Hope this helps and best of luck.

Thank you for submitting your question regarding your cats. This can be common after a trip to the veterinarian. The kitten will be covered in different smells. This can cause stress in the older cat resulting in her to act out in aggression. Keep them separate unless they are fully supervised. They should be fine with each other in a few days. In the meantime, you can try a pheromone diffuser to help calm them. Feliway is a good brand. I hope this information helps!

This may be difficult to correct but it generally can be done. Continue using the diffuser. Try switching litter boxes, beds, and rubbing each cat with the same towel to try to get them to smell like each other.

The veterinarian can also prescribe medications which can help with aggression. I hope this helps and please feel free to post any additional questions.

How strange! I would consider trying some of the calming products such as a Feliway diffuser https://www.feliway.com/us/Products/FELIWAY-MultiCat-Diffuser and a calming supplement such as Zylkene or Composure https://www.vetoquinolusa.com/content/zylkene https://www.vetriscience.com/index.php?l=product_detail&p=9008103030

You are doing perfectly! The pheromone diffusers work great but it will take a few days to regulate. Be sure you have enough diffusers to treat the appropriate square footage of the house. I can't think of anything else to do other than getting the pheromone spray and not spraying it on the cats but just put some on a cloth and wipe a little on them each. That may help speed things along. You did great - hope they will start to get along again soon! Cats are funny creatures!
