Pet's info: Cat | Domestic Shorthair | Female | spayed | 2 years and 8 months old | 7 lbs

Hello Pet Coach. My 2 year old DSH white cat that I got from Cats Protection 3 weeks ago passes wind a lot,has a smelly bottom and will leave little bits of poo about. She uses the litter tray for big poos. I rang the vet and they said to stop all treats. That was 3 days ago and I stopped the dried biscuits and cat milk that mum was adding to her wet food diet yesterday. I feed her 2 pouches a day. She is 3.5kg. What else could I do to correct this problem please?

I agree with your veterinarian, it is very likely that this problem is dietary related. I would suggest to start feeding with a bland diet based on boiled chicken/white fish and rice in small portion every 6 hours for the following 4 days. Then gradually reintroduce the normal diet over 5 days. I would definitively recommend a veterinary check up if the signs persist or you notice diarrhoea, vomiting, lethargy or inappetence. Sometimes these signs may be related to gastrointestinal infection as well so an antibiotic treatment may in case be resolutive. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.
