Best protein treats for a growing Siberian kitten

A five-month-old Siberian is right in the thick of their fastest growth phase — it's a great time to be thinking carefully about what goes into their body. Cats are notoriously fussy about treats, and kittens even more so; they tend to go for strongly-scented, meat-based options and will usually turn their nose up at anything sweet or grain-heavy. The best treats at this stage are high-protein and low in additives, to support muscle and tissue development without loading them up with fillers. Is this mainly for training, enrichment, or just rewarding — and does your kitten have any known dietary sensitivities or allergies?

Perfect — chicken tolerance is a great sign, and at five months a Siberian is building serious lean muscle, so protein-dense rewards make real sense here. Before I point you to something specific: how big is he right now, and are you keeping an eye on his weight? Siberians are a large breed and can look deceptively lean while actually packing on mass quickly, so portion awareness matters even with treats.

2.3 kg at five months for a Siberian is solid — he's going to be a big boy. For a kitten at this stage who's tolerating chicken well and you want a clean, high-protein treat with no filler rubbish, I'd go with Natures Menu Freeze-Dried Cat Treats — specifically the chicken variety. They're made from 100% chicken breast, freeze-dried with no additives, no grain, no sugar, and nothing you'd need to look up on a label. Because they're freeze-dried rather than baked or extruded, the protein quality is genuinely high, which matters for a kitten still building muscle. They're also small and lightweight, which is ideal for frequent rewarding during training without overfeeding. You'll find them on Amazon UK easily, and they're well priced for the quality. One to watch: even with a clean treat, keep rewards to no more than 10% of his daily calorie intake — kittens this age have precise nutritional needs from their main food.

Freeze-dried treats are fine for kittens from around 12 weeks onwards as long as they're single-ingredient or near to it — which these are. The freeze-drying process removes moisture but doesn't cook the protein into something harder to digest; if anything, it retains more of the natural amino acids than heat processing does. The only thing to keep in mind is that because they're low in moisture, make sure he's drinking well from his main meals. Siberians as a breed can be a little prone to kidney sensitivities later in life, so building good hydration habits early is worth doing. But as a treat in normal quantities — he'll be absolutely fine.

Great choice. He's going to love them — freeze-dried chicken has a strong scent hit that kittens respond to really well, so they tend to work brilliantly as a training reward. Enjoy the litter training wins, and good luck with the rest of kittenhood — Siberians are wonderful cats once they're fully grown.
