I know you guys are going to tell me to take Chester to the vet on this one, which I definately am going to do, but I need an opinion on if you think we can hold out until the morning when the real vet is in so we can avoid the costs of the emergency vet (which, I will still take him to if he needs to go). Here is what happened:

Chester is 14 weeks old and extremely healthy. About 3 1/2 hours ago, he got one of those Hartz fuzzy catnip mice and ate about half of it (the inside contents and part of the outer fur) before I found it and took it away (I know, I already feel guilty enough). First off, I called the emergency clinic to find out if these are toxic and they wouldn't tell me, they just said bring him in for xrays. Well, now he's been throwing up about every 5-10 minutes for the past 45 min. His throwing up is happening farther apart now then they were initially, but he is only throwing up stomach acid at this point. He had a good solid bowel movement about 2-3 hours ago. Now what I need to know is 1) have any of you ever experienced anything like this ie: puppy eating something and then getting sick for a while 2) Does anyone have any idea if these are toxic to dogs? I've heard of cats eating them and being fine.
3) In your experience, can we hold out until the morning when the regular vet clinic is open if I watch him carefully?

I gave him some nutrical already. He is still fully alert, but is not interested in food or water (which is to be expected, I'm sure)
