Our Cat Neko is almost 1 year old (will be in March) she weighs about 7.5 lbs. She seems to try to cough or throw up but nothing seems to come up. We were told it could be hair balls, she does shed alot, she seems to be healthy other than that. There is no sign of blood , worms or anything in her stool. What do you do for hair balls? Thanks Sadie
