I was babysitting a 6 month old kitten named Scamper and he had a 3 in 1 hartz flea collar on. It was put on him the day he came to my house. The next day he couldn’t walk, and had a severe lack of brain function. He also refused to eat and drink for 4 days after the collar was removed. I washed the kittens neck and my 6 month kitten Bynx tried to lick the other kittens neck. Today Bynx won’t eat or drink. Bynx has trouble walking and has a loss of brain function. I’m so scared. I hope he makes it. The kitten i’m babysitting is eating now but is still having alot of trouble walking and the motor skills are still at very low level.
