Bio Guard is a supposedly gentle shampoo for cats & dogs that will not wash off spot on treatments ( we use frontline plus) We gave our 1 1/2 yr old cat a bath with it and within hours he was so sick I thought he was going to die. He started with drooling then just got VERY weak & VERY unresponsive. He vomited & was not eating (still isn’t) or drinking. He is now trying to drink but not taking in hardly anything at all. I gave him a bath in Dawn after speaking with a vet asistant. He said NEVER use anything but Dawn dish liquid on a cat. I have thrown the bottle of shampoo away & am thankful I hadn’t used it on my 6 1/2 yr old boxer. Not sure if our kitty is gonna get better or not but we are praying that he does. I just wanted to bring this BIO GUARD to everyone’s attention as well.
