Sometimes one of my cats vomits after eating something she really likes. Both my cats like the Whiskas food but they only get a little bit once per day. I suspect she's just eating too fast and that makes her throw up.
What happens when she vomits is that her brother comes running and starts to eat her thrown up food from the floor. Apart from the fact that it is practical for myself as I don't have to clean up the mess, should I allow one cat to eat the vomit of the other one? Is it healty?
To the best of my knowledge she is not ill, she's been vomiting sometimes since I know her, and especially when eating very quickly.
