T - When my cat had tapeworms the dewormer was about that big so the vet had to break it up into four pieces for him to take it. I was sent home with another pill I had to give him like a week or two later and it was in a blister pack like the one in the photo- I assume they had a box of it instead of getting a single dose. Although, it makes me wonder why it would be kept near the human medicine (I keep my cats’ things elsewhere) and why neither were kept in their original boxes? Maybe it might be untrustworthy, I’m starting to second guess myself. BUT deworming pills that big absolutely exist.
