Buzz this time. He has been very grumpy and mean for the past few days. He started beating up on my other cats and yowles and hisses at us for no reason. Last night I attempted to pill him, worms again, and he tore me to pieces. He literally attacked and shredded my right arm and hand. I have about a dozen puncture wounds and about 30 scratches give or take. Some are pretty deep. What could be wrong with him? He has never behaved that way. He is/was the sweetest laid back little guy and would let you do just about anything to him. He is indoors all of the time. We have not switched his food, which he is eating. I will make an appointment for the vet but that can't happen until this coming Saturday. Until then, any ideas on what is wrong with him?
