Hi guys I got a problem. Today I found Tidus with his face in a 1/2 opened can of cat food I found. I own 2 cats at home and I guess they knocked over a can and the collision with the floor opened the can. The food was rotting and had what looked like worms on it. Maggots? I dont think so, I think it could have been Tapeworms. Anyways I'm gonna watch Tidus closely today and check his stools and the fur around his anus. The only thing is that Tidus has HeartGuard and I remember the vet telling me that it kills other worm along with heartworms. Is this true? Tidus is scheduled for another heartworm med. this week, I'm thinking about giving it to him today. I am not gonna shy away from the vet. check-up though if he does end up having worm, but I wanted to know if heartguard fights them too?
