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’m so sorry to hear about your dog. I think that anytime your gut tells you to get a second opinion that you should listen. I hope things turn out ok and I apologize for the delay in answering.
