No, it's not another Blackie case. In Blackie's case, he vomitted food early in the morning, after his breakfast. This has happened before particularly after he jumps & runs around immediately after eating. But in the evening, he vomitted a second time, this time just a pale yellow colour. So that was why I got really worried and started googling for "help" on the internet.
I read that if the cat is active and playful, it should be ok. So, I played with him immediately to see if he's active, and he was very active and eager to play. And he hasn't vomitted since. So, it's different from Lyn's friend's cat.
I attributed Blackie's second vomit to the fact that he didn't eat his lunch or dinner that day. I had changed his plastic food bowl to a stainless steel bowl and he was afraid of his own reflection in the bowl. But finally, at 10-ish that same night, he started to accept that the cat in the bowl is not going to bite his head off, and began eating normally. Phew!
Lyn, is your friend's cat still vomitting? It's
NOT normal for a cat to keep vomitting.
