OK, I just discovered a tapeworm problem in one of my outside cats. My dog is being treated for it monthly as the vet found some in august along w his heartworm treatment. Looking back on it, I bet that was a tapeworm in my roosters poo when I found him dying on my coop floor. Also probably why my birds I can't catch and dose (guineas and older peas) are not looking well. Question for anyone who might know, is there any way to dose in their water for tapeworm. I read praziquantel. I can't use oregano on my cats as it makes them throw up, and some of my older birds are almost uncatchable. So I need a way to dose everyone! Aww crap!
