I have a cat that all day has been acting very odd. He sat in the restroom since this morning, just sitting in one spot, not laying down or anything. Almost like hes hunched over. He's less then a year old and is normally full of life..

About a year ago one of our kittens got into some anti-freeze and died, and now my grandma (who thinks someone poisned that cat) is thinking this one got into anti-freeze too. Erm what do you think?
