I have three cats, one is a male who is 4 years old. He was just the sweetest cat until my nephew visited us 2 years ago. ever since then he has been EXTREAMLY agressive when babies/kids are around. He scratches and has nipped at any baby/kid we have around. I am currently 27 weeks pregnant and afraid that he will be just as bad with the new baby. has anyone else experianced this? how should I curb his agressive behavior? I don't want to get rid of him, but i will if i have to. I could use some help. Thanks
