Need a bit of help and advise please I have a 17.5 year old spayed female cat. She has a form of in’s non diagnosed but most of her life she has had the off few days episode of diarrhoea with fresh red blood been to vets numerous times over the years but no one has put 2+2 together 2 years ago I changed her food to hi life and hey presto normal stools ever since. 10 days ago she started going to every litter tray in house and doing a little pee then going in places she shouldn’t wouldn’t settle. Took her to vets and she was diagnosed with a uti and gave her antibiotic injection did bloods all normal except they found her thyroid was slightly and mean slightly over active advised to start her on thyronorm tiny 0.25 mls twice a day. We started with once a day a couple of days later Saturday night she started straining to poop we thing she had soft watery stools in 4 of our litter trays straining to go out of box where ever she could and tiny drops of fresh blood we gave her some loxicom and she settled down she was back to normal for 2 days then last night she started again small amount of watery soft poo licking herself a lot in that area no blood . Gave her loxicom again and she settled we are going back to vets later today. Not sure what’s up wondering if she is impacted now and by passing small poo or what it is anyone any ideas?
