Stop kitten stealing senior cat's prescription food

A kitten raiding a senior cat's prescription food is one of the most stressful multi-cat feeding problems — and it's not just annoying, it's genuinely risky if that kibble is managing a health condition. The most important features in any feeder are portion accuracy, ease of cleaning, and mechanical reliability, because cheap feeders jam, dispense erratic amounts, and harbour bacteria in crevices you can't reach. Before I point you toward anything specific: what's the prescription food for — kidney disease, urinary issues, weight management? And is your senior cat already microchipped or does she have an RFID collar tag?

That makes this urgent — renal kibble is calorie and phosphorus controlled, so the kitten eating it and your senior missing meals is a problem on both ends. A microchip-activated feeder is the right solution here, not a timed feeder. The lid only opens for the registered microchip, so the kitten physically cannot access it no matter how determined she is. One thing to know: does your senior cat tend to eat quickly when she does get to her bowl, or does she graze slowly? That affects which model I'd suggest.

Perfect, that confirms exactly what you need. I'd go with the SureFlap SureFeed Microchip Pet Feeder. It opens when your senior approaches and closes the moment she steps away — so the kitten can't opportunistically sneak in during those gaps. It reads her existing microchip directly, no collar tag needed. The bowl is shallow and wide which suits cats on renal diets who often have reduced appetite and prefer to approach from different angles. The whole unit comes apart easily for a proper clean, which matters a lot with prescription wet or dry food. It runs on four AA batteries and lasts a good while. You'd just place it in her usual feeding spot and register her chip via the button on the unit — takes about thirty seconds. One practical tip: feed the kitten on the opposite side of the room simultaneously so she's distracted and your senior has a calm window to eat.

It works perfectly well with wet food — the bowl is sealed when closed so it also keeps the food fresh and stops it drying out, which is a genuine bonus for a grazing cat. Just rinse the bowl after each wet meal because the lid mechanism can get sticky if wet food residue builds up around the rim. SureFeed also sells a sealed bowl version that creates a slightly tighter closure if you want extra odour control, but the standard model is fine for most situations. Given your senior's kidneys, keeping her food fresh so she's actually motivated to eat it is worth taking seriously — cats on renal diets can be picky about stale food.

Yes, I'd recommend it — not because the kitten needs a locked feeder, but because having two dedicated stations removes all competition and stress around food entirely. A simple timed feeder or even a standard bowl works fine for the kitten since her food isn't restricted. The main thing is physical separation so your senior always has a calm, uncontested place to eat. That stress reduction alone can help cats with kidney disease maintain better appetite, which your vet will likely appreciate too.
