Have Cat Questions? Ask a Cat Vet Online.
Hello, I'm Dr. Deb.
I'm sorry for this concern for your pets.
I do have a few additional questions to ask first if you don't mind:
1. Do you by any chance know what kind of worms your son's cats have or had?
2. Do you know if they were treated for them? If so, when?
There may be a slight delay since I have to type up a response to you. Thanks for your patience. Deb
