I got a look at Peppers poop tonight and it was loaded with tape worms. My Vet is only at night, but it's still hard for me to get there after as I take the bus everywhere. I've heard the over the counter tape worm stuff work, but is there one you can suggest that might be sufficient? Also my b/f said I should worm all of them seeing as they all share the same cat box. I think this is right, but info would be greatly appreciated.
