Puking Kitten!

We got 2 (brother) kittens about 2 weeks ago. They're about 16 weeks now. One of our adult cats didn't like them so much at first, but the Feliway seemed to make a huuuge difference with that, and they now seem to fit in just fine. One of the kittens has been puking like crazy though. He didn't throw up at all that I know of for the first several days when we had them locked in the bathroom. I was giving them both wet food and dry food (the same kind they were feeding at the shelter to help transition). But now that they're out and about with the adult cats, poor Clarkson is always throwing up. I suspect that he may be eating too fast. If they don't finish all their food, our adult cat Mike acts as the garbage disposal and walks around and eats up everyone else's food. So I think Clarkson may naturally be a grazer - eating a little here and a little there - but since he knows Mike will eat his food, he's forced to just stuff it all down at once or else risk having Mike at it all. And that's causing him to get sick. At least that's my theory. He could just be rejecting this particular food or have an allergy, but I don't really know how to tell. He pretty much throws up very shortly after he eats. I actually thought he had *stopped* puking until today I heard him crying in the litter box and went over to see what was going on annnd...he puked his guts up right in the litter box. Very convenient, I might add, however if he's doing that, I have no idea how often/how much he's doing it since it's pretty difficult to tell the difference between pee and his watery puke in the litter. Any ideas here? Is it a problem if he eats adult cat food? The cats are constantly going from one plate to another I can never tell how much actual kitten food he gets versus cat food.

Allllso...One of the kittens (not the puking one) has developed acne along with one of my adult cats. Do you think that's all stress related? And how do I make it go away? Do I need vet care for that or is that something I can take care of on my own?

What food are you feeding? Raw is best, but some of the high quality grain free formulas are acceptable if you prefer dry food. I ask because both feline acne and a sensitive stomach can be caused by low quality food. My boy cat used to puke after eating until I switched him to Orijen which is grain free, now he rarely pukes. Same with my kitten, if she ever gets into the junk treats I bought for my older ones that have grains she gets really sick for about a day. Cats are not naturally grain eaters, so certain cats get very sick when they are fed it.

Also, what bowls do you use? Plastic bowls can cause acne as bacteria gets trapped in microscopic scratches in the material and when the cat rubs against it when eating it can cause acne. When my cat Pooka had acne really badly I ended up having to shave her chin and use a mild cat friendly soap followed by witch hazel to clear it up...however it doesn't usually require a vet.

They're all eating Wellness canned stuff. I was leaving some dry out for them too since that's what they were eating at the shelter to help them with the transition. (Some icky Purina One I think it is.) 

They're eating out of glass bowls/saucers already What kinds of soap are cat friendly for me to use on him?

Is he pooping? Puking in the litter box may be bcause he was straining to poop, it hurt (crying) and caused him to vomit.

I recommend a trip to the vet, without delay. Kittens can go downhill fast.

He was pooping in the litter box just fine. But when he ate, he would eat too fast (I think?) and then throw up all over the floor. He did this for 1-2 days, then we stopped seeing him puke and stopped finding puke on the floor. We thought he had either a) stopped eating too fast, or b) finally adjusted to the food we've been feeding him. Then, the day I started this thread, I heard him crying and walked in in time to see him puke in the litter box. Of course I can't know for sure, but it didn't appear that he was trying to poop first. Hubby and I have both been off work the last 2 days and have been watching him closely and haven't seen him puke at all - in the litterbox or otherwise. And he is still pooping. So I'm not sure what's up, and it may have resolved itself?

Ack. I was doing some more research on the acne thing and every case I read about, they have it on their chin. The stuff my little guy has is on the sides of his face...like in his whiskers. Can that still be acne? It looks really similar to the pics of mild acne I'm seeing, just that it's not on his chin...

Flowerbelle had acne just above her whiskers. :nod: I used 500ppm colloidal silver on it - cleared it up overnight, actually. I used it for two days, just in case (topically). I just put a few drops on my finger and rubbed it on. :dk:

Many recommend washing twice a day with Hibiclens - available at any pharmacy.

Hope there's no more puking!
