Birman Senior Feeding Calculator
Senior Birmans often need a different calorie balance than young adults as activity and lean mass change. Typical adult weight for this breed is about 3.5–6 kg, but always enter your cat’s current weight and honest activity level. This Birman senior feeding calculator uses veterinary RER and MER formulas with a senior life-stage factor. Recheck portions after weight or lifestyle changes, and work with your vet if your Birman has medical dietary needs.

- If activity has dropped, choose a lower activity setting and reassess after a few weeks of weigh-ins.
- Senior diets can differ in protein and phosphorus; follow your vet if a clinical diet is prescribed.
- Recalculate after dental issues, arthritis limits activity, or medication changes appetite.
- Weigh your Birman monthly and adjust portions if body condition drifts from ideal.
- Split daily calories into three measured meals to support steady energy and digestion.
