We've had this shitten since she was about 8 weeks old. She's now 9 months and has been neutered recently. She had an upset tummy and a bit of a runny bottom and crapped on the bed and the floor two weeks ago. I thought it was because she couldn't make the litter box on time, took her to the vet who put her on Felidiarix and it cleared up. Two days after she finished the course of tablets, her poo got runny again and she crapped on the bed and in the bath. I decided to change her diet, took her off soft food and back onto the dry cat food. She complained initially but the poo hardened up back to normal. Result, I htought. Today she shat on the bed again - it wasn't as solid as it could have been, but wasn't diarrhoea like she had the other week. She did the same thing yesterday on the bed, and the day before in the bath. Her litter box (which she has always shared with the other cat) is clean. I have run out of duvets and can't carry on like this - any ideas? She and the other cat sleep on the end of the bed. She has always been clean up till now.
