Hello,
Is everyone spayed and neutered? That might help settle down of the stress?
After that make sure everyone is healthy. At my clinic this would include an exam on all of the cats and perhaps even blood work.
Then we talk about a more gradual acclimation period. I’ve seen this be between two weeks to years. Cats are their own bosses. So they decide on their own terms
Good luck.





Hello,
I am so sorry to hear that you are going through this. Unfortunately, once a kitty has a blockage, we typically see it reoccur in some cases. I would highly suggest that you talk to your vet about a PU surgery (Perineal urethrostomy). It is a surgical method for alleviating a urethral obstruction. We also always recommend switching your cat to a veterinary recommended Urinary diet for the rest of your kitty friends life.
Hope this helps some!
To add to my original response, I would talk to your vet about fluids and pain meds to do at home. Also, if your kitty will eat wet food, We highly suggest it over dry.
