I recently noticed a white worm on the tail end of my cat. I have tried the Hartz wormer, both liquid and pill form, but it doesn't seem to help. I have two other cats also. What should I use? Do I have to treat them all?
I recommend that you treat them all. I do not know what type of worm this is b/c most worms are white. I recommend you bring a stool sample to the vet so you can find out the type of worm and the proper mediation can be given. Vetcare
