Solved his bad tummy !
I have two 7 month kittens and one has been a nightmare to feed as he is so fussy and they other has had such a bad tummy all good goes through him. I had one on RC gastro for his tummy (which he wasn’t keen on, but did the job) and the other on whatever he would eat! I had to feed them separately which was hard work…anyway I bought Whiskas for a barn cat which I feed and my husband fed ours by mistake, well they both ate it AND no diarrhoea! 2 weeks on this and they are still happy, hallelujah
