Unsure of the cats age, we took him in when a family member died and she took him in as a stray we would guess around 12 to 14. The last week or so he has hardly touched his food and as a result has lost weight already. Its very unusual for him as he is constantly begging for food normally. Today he pood on the floor and it was slightly runny. Went out and he had attempted to go again in his litter tray but missed. Was a small amount of poo but very runny with a jelly like consistency. Any ideas anyone? Will be ringing my vets tomorrow!
