2 month old kitten, diarrhea HELP!

Hey everyone,
So I need some help and advice..
Two weeks ago I got a female silver Bengal kitten, she's 2 months old on February 2nd. She had diarrhea the first day or so when we took her home and knew it was due to new food. she is being fed Blue Buffalo for kittens. A few days later I watched her take soild poops. But now shes been having diarrhea ever since then, her activity level hasn't changed at all, she's hyper playful cuddly she purrs etc. She does eat a lot and goes back and forth from her bowl of kitty food to my older cat adult food which is also blue buffalo. About 3 or 4 days ago we gave her a spoon full of cow milk and she ate a little bit of grated cheese that fell on the table, and the next day got licking my spaghetti plate when I was finished but I quickly stopped her. Her poo is brown and didn't have anything off to it until about half hour ago when I seen a little bit of blood on the top sorta swirled in it, not a lot though. We took her food bowl away right after we seen it and are going to keep it away for 12 hours like we have read on forums. Since we have got her she's gotten a little pot belly from eating it doesn't look like its bloated or anything.

Please help! If we see another poo with blood we will take her in.

If any further info is needed let me know

My first thought with a kitten this small is parasites.  It often takes multiple dewormings with kittens. 

Cow's milk often is an issue for kitties.  It's less likely to cause issues with kittens but it still can be a problem.  It can make diarrhea worse.

Did she come from a shelter or rescue, or was she from a breeder? Rescue kittens often have intestinal parasites. Some parasites can cause blood in the stool and diarrhea, and they may be exacerbated by change in diet/stress. You can feed her chicken baby food (with no onions) or plain boiled chicken for now, which are very bland and don't have the carbs that cat food has that will feed the parasites. I think a vet visit is in order just to get the medication if she does have something. 

Definetely sounds like parasites. 

Get the vet to do a fecal smear to rule out Giardia.  They may even opt to do a flotation.

Don't try to treat parasites OTC.  It never works and it might just hurt your cat.

I agree that it's likely parasites.  Definitely be careful about her getting into human food.  Cats can't digest dairy and it cant upset their stomachs.  Also onion and garlic are toxic to them, and likely in tomato sauce.

I also would suggest you don't withhold food from such a young kitten.  She's really too young to go without eating for any period of time.

I with held her food that night and she didn't poop but she drank lots of water, as soon I as gave her the food back within 20 minutes she was having diarrhea. I got her from a breeder.
I made some plain white rice and have been feeding her that with a bit of her food mixed it, she's still having diarrhea. I've looked in every poo she's had and it's just been brown nothing else. Except that one poo where there was a little bit blood. She hasn't had blood in it since.

If it was any kind of parasites would she be as active as she's been? She isn't showing any signs of not being well. I also have another cat, would he be at risk for getting them if she has anything ? They have separate litter boxes and the only time she has gone into his is if she can't get up stairs fast enough to use hers, other than that she's been making it to hers every time. We scoop the box out if ahe happens to go into his.
I've looked at her bum and there isn't anything around it that looks unusual.
She eats a lot, and Shea been gaining weight if it was parasites wouldn't she be loosing weight or would it make her bloated ?

These are all questions that you should ask your vet. I'm worried that she's not having her nutritional needs met because she's having so much diarrhea and having a restricted diet. It could be parasites and she should really see a vet. Once you rule that out, it could be a protein allergy and she could need different food.

I agree, a vet visit is in order. Parasites come in all different forms. A tapeworm would cause noticeable weight loss to be sure, but microscopic parasites like giardia or coccidia are less likely to show symptoms other than diarrhea. It takes an awful lot to keep a kitten from playing! If the two cats don't share a litter box the chance of the other one getting it is lower, but if they groom each other he still could get it. Be able to describe the color and consistency of the diarrhea to your vet to help with a diagnosis. Even if it isn't a parasite, the vet will have better suggestions for how to identify and solve the problem.
