Hi,
You have to get your cat to a 24 hr. Emergency animal hospital, now!
Throwing up is getting rid of some of it, but you don't know if pieces of the toy are going to get stuck somewhere internally and cause an obstruction, or if any pieces are wrapped around any organs like the stomach, intestines, etc.
Was the mouse totally fuzzy--like all soft material, or did it have any hard parts and/or strings, (whiskers, tail, ribbon, wiggle eyes, bell) etc.? Also, did it contain catnip inside?
Do you have another one so you can show the vet what he ate? They'll most likely do x-rays to see where the parts of the toy are and then recommend treatment.
Please let me know how it goes at the vet! Good luck!
