I'm no expert but whatever you do don't give the cat milk.Most people don't realize that most cats are lactose intolerant.This will cause diarrhorea.make sure she has plenty of cool water.

Make sure she has water to drink. If it is not getting better within 24 hrs., you need to take her to the Vet. Dont give her aspirin, it can make her very sick.
You can give her a little boiled rice with boiled chicken .

NO ASPIRIN FOR CATS!!!!!  Dogs are more tolerant of people medicine than cats.  It is most likely something he/ she ate.  Clean water and just a bit of dry food for now.  Hot ears and a dry hot nose are two other signs of dehydration/illness for cats.  Might take a day or two but she'll probably be fine as long as the diahreah is occasional- if she is going non-stop a visit to the vet might be in order.  I've had cats my entire life and only once did it signify a bad disease.  

Is your cat still eating?  Loss of appetite is a sign of real illness. Could be it just has a case of the runs......

Dehydration is the symptom of diarrhorea that makes you feeel even worse.She is certainly dehydrated if she has diarrhorea. Just as an afterthought Itsmee,my late uncle (who was a dog expert) used to give his dogs an aspirin if they were a bit off colour. He used to race greyhounds.He reckoned it couldn't hurt.Might be worth a try.Hope poor old puss fels better soon. Good luck.

I was going to say what Tommy did.........that giving a cat milk might cause the runs......so can chocolate. Maybe if your cat went outdoors, it ate or drank something that gave it the runs. It's probably natures way of cleaning out your cat's digestive system. But,, if it continues after say........3 days, then take it to the vet.

My cats have had it a few times, as everyone says it's probably something the cats eaten. If it still has it after a couple of days take it to a vet. treat the cat as you would yourself eat food but not too rich, and plenty of water.

Oh, Peeve is an inside cat. I lost a cat by letting her run outside in the woods. It was almost impossible to keep her in the house. I swear, she’d knock you down getting out. Anyway, she thought she was a raccoon and that just didn’t work for her. <sob> 

easy way to check for dehydration, gently pull up the scruff of the neck then let go, if the skin springs back quickly all is fine,if the skin is very slow to respond the cat is dehydrated.
