Urinary health for neutered male kittens

Your vet is right to flag this early — neutering does reduce metabolism and can change urine concentration, which raises the risk of struvite or calcium oxalate crystals forming, particularly in male cats. Male cats have a narrow urethra, so a blockage is a genuine emergency, which makes prevention the smart move at this stage. Urinary issues in cats are heavily diet-driven, and getting the right food in place now — before any problem develops — is one of the most effective things you can do. To point you in the right direction: is your kitten showing any symptoms at the moment, and what are you currently feeding him?

Good that there are no symptoms — this is exactly the right time to act, when you're ahead of the problem. The one thing I'd want to change straight away is the all-dry diet. Dry food means your kitten is getting very little moisture through his food, and dilute urine is your first line of defence against crystals forming. Siamese cats can also be prone to lower water intake naturally. Can I ask — does he drink much from his bowl, or does he seem to ignore it?

That's very common in cats — they evolved as desert animals and have a low thirst drive, so they rely on food moisture to stay hydrated. A cat eating only dry food is almost always mildly dehydrated, and that concentrates the urine, which is exactly the environment where crystals form. My recommendation is to introduce wet food as the main part of his diet now. The specific product I'd point you toward is Royal Canin Urinary Care wet food in gravy pouches — it's formulated to maintain a urine pH that discourages crystal formation, has controlled mineral levels, and the high moisture content does a lot of the protective work passively, without relying on him to drink enough. It's also a Royal Canin product so the transition from his current food should be smooth. You can keep a small amount of dry as a supplement if you want, but wet should be the foundation.

Good question. The Royal Canin Urinary Care wet formula is designed for adult cats, and ideally you'd wait until around 12 months to make it the sole diet — kittens do have specific nutritional needs for growth. What I'd suggest is a practical middle ground: transition him onto a high-quality wet kitten food now to get that moisture into his diet, and then move onto the Urinary Care formula once he hits 12 months. If you want to add one or two Urinary Care pouches a week alongside a kitten wet food before then, that's reasonable, but don't make it 100% of his intake just yet. The most important thing right now is simply getting him off an all-dry diet.

At this stage, with no active problem and a diet change in progress, I wouldn't layer in supplements yet. Wet food with the right mineral balance will do more than most supplements can. The one thing worth considering in a few months, once he's on the Urinary Care formula, is a water fountain — cats are much more likely to drink from moving water, and keeping urine dilute long-term is the whole game with urinary health. But sort the diet first. That's the foundation everything else sits on.
