My cat has tapeworms. I have a bad general phobia of parasitic creatures (yes, I know contracting them myself is rare, and that's not my phobia.) I fed her her pill at ~830 PM last night. She just puked (on my bed, of course) at 520 AM. Does anyone honestly know if this was enough time for the worm pill to do its thing? I can't tell from the puke. I'm so stressed out.
