Frequent litter box visits in an 11-year-old cat is exactly the kind of change worth taking seriously — it's one of the earliest signs that the kidneys may be under stress, and cats this age are squarely in the window where kidney disease, hyperthyroidism, and diabetes start to show up. Cats are brilliant at masking illness, so the fact that you've noticed a behavioural shift puts you ahead of most owners. Can I ask — how long has this been going on, is he or she producing a lot of urine each visit or just straining, and has your vet seen them recently?
It's been about three weeks. She seems to be producing urine fine, just going much more often than she used to. No straining. The vet did bloods about six months ago and everything was normal, but that was before this started.

That's a helpful distinction — producing urine without straining points more toward increased thirst and output rather than a blockage or UTI, which is actually the pattern you see with early kidney disease or hyperthyroidism. Both conditions cause cats to drink more and therefore urinate more. Six-month-old bloods are worth revisiting now given the new symptom; kidney values in particular can change relatively quickly at this age. In the meantime, is she eating and drinking normally, and have you noticed any weight change or a change in how vocal she is?
She does seem to be drinking a bit more now that you mention it. Eating well, maybe slightly thinner but I wasn't sure if I was imagining it. She's been a bit more vocal lately too, which I thought was just a phase.

You're not imagining it — increased thirst, increased urination, weight loss despite good appetite, and becoming more vocal are the classic four signs of hyperthyroidism in older cats. It's the most common hormonal condition in cats over ten. The good news is it's very manageable once diagnosed. I'd get her to the vet this week rather than waiting; a simple blood test checks thyroid levels alongside kidney function and the two together will give a clear picture. While you're waiting for that appointment, is she on any particular food at the moment?
Just a standard supermarket wet food mixed with some dry. Nothing specific for seniors.

Given what you're describing, this is a good moment to switch to a renal-supportive diet regardless of what the bloods show — it takes pressure off the kidneys, which are almost always involved to some degree alongside thyroid issues in cats this age. The one I'd recommend is Royal Canin Renal dry food for cats. It's low in phosphorus and has controlled protein levels, which is exactly what you want to reduce the workload on the kidneys without starving her of nutrition. It's widely available on Amazon UK and your vet will likely recommend something similar once they see her results. It won't interfere with any treatment she might need and it's a straightforward upgrade from what she's on now. Keep her well hydrated too — if she's not a big water drinker, a cat water fountain can help encourage intake, which matters a lot for kidney health.
That's really helpful. I'll book the vet and switch her food. Is there anything else I should be tracking in the meantime?
inparticular.ai
Yes — keep a simple note of roughly how many times she uses the litter box per day and whether the volume looks large or small. Weigh her weekly if you can; a kitchen scale works fine for cats. And note whether she's eating all her food at each meal. That's genuinely useful information for the vet and means you won't be guessing from memory when you're in the consultation. You're already doing the most important thing by paying close attention — catching this early makes a real difference to how well these conditions are managed long term.
