a year and a half ago i found a kitten an she had worms. We got rid of them but then she got them back. So its been like a year and them she started to have blood in her poop. So we took her in really quick and got her dewormed again. But shes acting wierd and i was wondering can a cat die from tape/roundworms if they've had them in their system for all their 1 1/2 years of life?
