Vet-recommended litter tracking for senior cats

So your vet has flagged that your 10-year-old cat's litter habits are worth keeping a close eye on — that's a really sensible heads-up, especially at that age when kidney issues, diabetes, or urinary problems can show up first as changes in how often they're going or how much. A self-cleaning box with app tracking can genuinely help here, because it logs each visit automatically so you're not relying on memory or guesswork. That said, they're a significant investment, they need clumping litter, and older cats can sometimes take a little time to accept a new box. Before I point you somewhere specific — is this your only cat, and do you have a sense of budget? Also, did your vet mention anything specific they want you to watch for, like frequency, volume, or both?

That context is really helpful — if the vet is looking at kidney disease or hyperthyroidism, tracking urination frequency and volume changes is exactly what you need, and this is honestly one of the best use cases for an app-connected litter box. It turns into a genuine health monitoring tool rather than just a convenience gadget. Can I ask: is Marmalade currently used to a covered or open litter tray? And is she generally an anxious cat, or fairly adaptable to new things?

Perfect — that makes this much more straightforward. A relaxed cat who's already used to a covered box is a good candidate for a self-cleaning unit, and the transition should be fairly smooth if you do it gradually alongside her old box. Given what you've described, I'd go with the Litter-Robot 4. It's the most capable app-connected litter box available in the UK right now — it logs every visit, tracks weight at entry (which is useful in itself given Marmalade's weight loss), and gives you a clear usage history you can screenshot and take straight to your vet. The app will flag unusual patterns, which is exactly what your vet is asking for. It sits just under your £500 budget. The globe design is enclosed, which Marmalade should find familiar, and the opening is generously sized. You will need good clumping litter — it won't work with crystal or wood-based — but that's easy to swap. I'd keep her old box nearby for the first week or two just while she adjusts, then remove it once she's consistently using the Litter-Robot.

Genuinely one of the better pet apps out there — the usage history is clearly displayed, you can see timestamps for each visit and get notifications if there's a long gap or an unusually short cycle. Some users find the initial Wi-Fi setup takes a couple of attempts, but once it's connected it's reliable. The weight tracking isn't a substitute for a proper vet weigh-in, but it's a useful pattern indicator over time. For what your vet is asking you to do, it gives you real data rather than a rough impression — that's the key thing.

A few practical things: use a clumping clay litter, not too fine or too dusty — something like Catsan Clumping or World's Best Cat Litter works well with it. Fill to the marked line inside the globe, not more. Run the unit with the old box alongside it for at least a week — don't remove the old one too soon, even if Marmalade seems keen. And once she's settled, take a screenshot of a week's usage history before her next vet appointment — that's exactly the kind of data they'll find useful. I hope Marmalade's results come back reassuring.
