Pregnant and lactating cats need more calories to survive. Resting Energy requirement (RER) is the best way to calculate cat’s calories, once you have calculated RER you can easily calculate cat’s Daily Energy Requirement (DER) which is the count of many calories your cat has taken each day. Always concern your vet for further more advice about your cats related to weight gaining and weight loss. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerLeave an answerCancel reply Attachment Select file Browse Featured image Select file Browse Save my name, email, and website in this browser for the next time I comment.
