Problem solved
My 4 kittens are aprox 9 week old, they were having problems with runny poop, they had been wormed, had antibiotics and some paste to sooth ther gut all ofvwhic had no effect. They had been eating just wet food ( animonda carny). After doing some research i fould some info the bucked the trend saying cereals are all bad for kiitys as they cant digest them and so having tried varios other dry food which they turned their noses up at. I bit the biscuit and bought smilla due to the meat/maize/rice/yucca ingtedients. Since mixing this with their wet food, the runny poop has nearly all cleared up after just a couple of days. I soak them in water (this softens them and increases there wayer intake) and mix with the wet food and they cant get enough, price per kilo also makes these cheaper than even tescos own kibble. Go with your gut, if your feeding a grain free wet food i think theses are really good along side the wet. If your just going to feed dry food i would consider buying a brand thats grain free and feeding that mixed smilla and some other higher quality kibble.
