6 week old kitten diet

Hello, I'm brand to this site & looking forward to meeting other cat/animal lovers like myself!
Anyway, last Friday my boyfriend brought home a 5-6 week old kitten. A woman had brought them into work. Their mom was hit by a car, they were not completely weaned & she said they were all eating canned food for a week. So he picked up Friskie's canned food. We were feeding her a tbsp 4-5 times a day, as the woman suggested. Her stool was pretty solid & formed. I didn't think that food was good for such a small baby so we switched her (gradually) to canned Chicken Soup for the Soul cat food, kitten formula & Earthbound (for cats & kittens) dry. Her poop got runny, than solid, than runny again. Otherwise she is very playful, eats like a champ, uses her litter box very well, its just the runny poop. She comes when you call her & is very alert, overall seems happy, healthy, everything a kitten should be. I know she needs to see a vet soon but in the meantime, what would be the BEST diet for her? Have had cats/kittens in the past just not this young..suggestions?
P.S. I have owned cats/kittens before just not so young. I own 2 small dogs & they are fed high quality dog food so want the same for my new baby.
Thanks alot :-)

I'm bumping up this thread since no one has answered it yet.  I would think both of these would be fine for a kitten, although I'm no expert in kitten care.  Gosh, she is awfully young, poor thing .  Are you supplementing with any KMR or goats milk or anything (as I said, I'm not a kitten expert, so just asking so when one of the folks who ARE will not need to ask ).

She may have worms, which could be causing the diarrhea.  I think it's very common for young kitten to have them.

That age she should be eatting solid wet food i got the best food i could find at kroger and started letting it soke in water so he could have dry food likke his mother when he was about 8 weeks wet kitten food of any kind is really good for them but i would make sure there is real meat as the first or secound iningreediant. I am feeding my cats nine lives cause that out of all of them is the best food i could get them to eat and that they enjoy. Friskies i could only get them to eat the wet. There must be something in the dry that neither of them like so try the best cat food you can gset for a kitten mix with some kmr and sit back and make sure she has plenty of water she will be ok

 hi Jezebel.   The Chicken Soup is probably be OK.   maybe a bit high in carbs?  but  i think under 10%.  

The Earthborn  ( is that what you mean?  I know a food called Earthborn.   Is there a different one called Earthbound?)   unless it is their grain free kind,  is way higher in carbohydrate  than I would want to feed --  at least according to this http://www.naturespetblog.com/2011/07/earthborn-holistics.html   it is  36% carbs.   (  which makes it over 10 times what a cat's natural diet would be.) That one has got rice and oatmeal and peas.   that's a lot of starch.   If she started eating more of that,  that could be what is giving her some loose stools.   ( Actually even the " grain free"  dry foods are usually  pretty high carb for a cat.   The Earthborn grain free dry is i think around 17% carbohydrate which is similar to most of the " grain free" dry cat foods.  ) 

  It may be that her poop first got runny just because of changing.. then firmed up... then if she started eating more of the dry food,  that may have caused it to get soupier again.  Dry food nearly always has more starchy ingredients -- grains and/or something like potatos or peas --  to make the pieces form into kibble...   and cats'  bodies are not made for eating such foods,   so if she started eating more of that, it could be upsetting her digestion a bit.  

 You could try going back to more canned food.    

Another thing you can do is add a bit of canned crushed pumpkin to their food. just like a spoonful.  . It may not seem to make sense but that can actually help with both constipation and runny poop.  

Another idea is probiotics.  Here is a recent thread dealing with that  http://www.thecatsite.com/t/262587/probiotics-search-human-grade-and-cfus

 Just in case you are curious  here is what I usually feed my kittens . ( I'm not saying these are perfect or the only acceptable commercial foods ) 

Canned: Wellness in  chicken or turkey 

              Merrick Purrfect Bistro pate style in chicken, turkey or duck.  

 Raw frozen:    Natures Variety Instinct venison 

Dry :  Natures Variety Instinct Chicken  

Those are " all life stages"  foods. 

 I do find that the raw   helps to firm up their poop. 

Ideal would be probably homemade raw IF carefully balanced and prepared. .   

 If you are interested in making your own   see the nutrition forum's section on Raw and Home-cooked food  http://www.thecatsite.com/f/65/raw-home-cooked-cat-food

 A great site from a vet with a lot about cat nutrition  http://www.cainfo.org     includes a section on Making Cat Food with recipes .

 Another recipe from a breeder & author of Raising Cats Naturally  http://www.blakkatz.com/recipes.pdf

Otherwise  ..  if looking for commercial food,  you want high animal protein,  moderate-high fat,  very low carb.  carbs definitely under 10% of calories.   

   a 6 wk old kitten should eat about 4 meals a day.
