❓ Frequently Asked Questions

What is RER and MER?

RER (Resting Energy Requirement) is calories for basic functions. MER = RER × factor accounting for activity/body condition.

How do I assess BCS?

Feel ribs (slight fat cover), check waist from above, and abdominal tuck. Use our 9-point visual scale.

My pet needs to lose weight. What status should I pick?

Where can I find calorie density?
