This happened with my two kittens, they both have JWB down all day then i gave them 2 whiskars pouches per day, they had terrible poo's
I came on here did some research into foods, and swopped whiskars to Natures Menu pouches (i give them 1 pouch between them per day) and give them Applaws and Hi-life as a treat every few days, within a week the difference was unbelievable!!
They have excellent poos!! I know its a bit more expensive but in the long run its totally worth it!! HTH x
