Sensitive dry cat food for older Siamese on a budget

Digestive sensitivity in cats is often down to food intolerance rather than a true allergy, and for many cats a limited-ingredient or novel-protein diet makes a real difference. For an older cat with ongoing loose stools, that's usually where I'd start looking. Can you tell me a bit more — how long has your Siamese been having this problem, what are you currently feeding him or her, and do you have a rough monthly budget in mind for food?

Four months is long enough to be fairly confident the food is the issue rather than a temporary upset. Supermarket own-brands often contain a mix of protein sources, grains, and additives that can irritate a sensitive gut — especially in an older cat whose digestion is naturally a bit less robust. Is she on any medication or supplements at the moment, and has she had a vet check in the last year or so? I want to make sure we're not missing anything before putting it all on diet.

That's helpful — vet-cleared and no underlying condition means diet is almost certainly the culprit, and your vet is right. For a budget-conscious option that genuinely works for sensitive older cats, I'd point you to James Wellbeloved Adult Dry Cat Food in the Turkey & Rice flavour. It's a limited-ingredient recipe with a single named protein source, no artificial additives, and no common triggers like beef or dairy. A 1.5kg bag runs around £8–9 and typically lasts a single cat three to four weeks, so you'd comfortably stay within your £20 monthly budget. It's also widely trusted for Siamese, who are a breed that tends toward digestive sensitivity anyway. I'd give it four to six weeks to see a clear improvement in stool consistency.

Gradually, definitely — especially with a sensitive stomach. Mix about 25% of the new food with 75% of the old for the first two or three days, then go 50/50 for another two or three days, then 75% new for a few days before switching fully. A slow transition gives her gut time to adjust and makes it much easier to tell if the new food is helping. If her stools are still loose after a full month on the James Wellbeloved, it's worth going back to the vet to discuss a hydrolysed protein diet, but most cats in her situation respond well within that window.

Good luck — I hope you see an improvement within the first couple of weeks. Siamese can be a bit delicate digestively but they also tend to respond well once you find the right food. If things don't settle after the full transition, don't hesitate to check back.
