And guests have even started to comment on it. One is far worse than the other he passes wind a lot and it's awful! The vet said to worm them again so we did to no change. I have tried fortiflora which offered a small improvement but switched to regutum as it's much cheaper but doesn't seem to be helping at all. Any suggestions anyone?! We are on felix kitten they have 2 pouches each a day with dry food available.
