Had to take him back to the vet today as he still has quite soft poo although not going as often. Vet gave him anitibiotic jab and a course of pills. Charlie got caught short in the waiting room - I knew cos he was meowing to get out of his basket and he never does this unless he needs the toilet. The vet nurse put him in a cage with a tray and sure enough he obliged. Then he stayed in the cage until his turn and watched the nurses. Seemed to be quite enjoying himself. The vet has given me some more Sensitive wet plus a bag of dry (Charlie wont usually touch dry but just to prove me a liar he wolfed some when we got home). Vet said should expect improvement by Wed but his bowels, whilst still quite full, are firmer. Fingers crossed for Charlie boy
