Hi got six cats and was wondering if i should use bayer tapeworm dewormer since its cheaper than the vet. Then i was reading reviews on chewy and got all scared one review said the cat got sicker and sicker and died=(. Can that happen????. Should i not go with this because of that? I dont wish death upon them=(. Anyone had a cat die from this stuff? Also does it work lots of reviews say it didnt=(.
