Sorry, was more like two weeks.. I got a bit ahead of myself there. Took the kitten to the vet, though they could not find anything viral. For several days it was having normal discharge of its light brown, stinky clumpy poos. Now today its back to runny, fart like poos that run like a lahar down a mountain side. The kitten does seem to be very playful, chasing toys as it should be and is now cleaning itself most of the time. There is still the odd occasion where we have to wash it because its running around with poop all over its butt,tail and leg.

Im not sure if this helps but the cat is half siamese, are they dirty by nature or is it just this kitty

We really want this sorted as its so nice to snuggle between us in bed.333333333333333333366666666666666662l;;;;;;;;; ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; <----- kitten was "typing"

I have had a similar thing with a previous cat but that was sorted after about a week and then it was fine. And ive also found that cleaning its litter box after EVERY poo makes it constantly use its box, except for today when it pooed under the kids bed :S

Thanks guys, any help would be great
