Okay, this may be a little more graphic than usual.... Tabby vomits much more frequently that Sashy. Tabby, however, always lets me know when she is going to be sick. She has this terrible howl-like sound that comes from the very bottom of her tummy... and I know it is time! She then makes the awful "dryheavish" sounds, and up it comes! At least I have some warning, and can move her, if necessary. Sashy, on the other hand, she is only 2, and has only gotten sick twice. But both times, there was no warning, and it was VERY projectilish! It was everywhere! Bless her heart. Both times, I believe, were a reaction to food that didn't agree with her. Tabby usually gets sick from a hairball or from eating too much grass. I live in a rental townehouse, so I am not too worried about the stains. I clean them as best that I can and we go on about our days! Sorry about the graphic descriptions!
