New kitten problems--puking

[lillibou]

It started out with Kiki. She puked three days ago. Eats fine, is active. Had some somewhat loose bowels, but is fine now. Now, this morning, Mew puked formula. But other than that, he's acting fine.

His b/ms are fine.

I can't remember if you said they had been to see the vet but I think a visit is in order. Have they been treated for worms? When they throw up do you see any spaghetti like things in it? If so - worms. It is a good idea to have them tested and treated.
Over the counter meds you can buy at pet stores, WM, places like that, do not work. It needs to be vet issued. But it is not expensive.
It's possible it is something else too. Better to nip it in the bud.
