How’s the Weight, Doc?

This is a question many pet parents, both kitty and pup parents alike, ask during their visits with their vet, but it’s probably a discussion that could still be had more often.

According to the latest 2018 results from the Association for Pet Obesity Prevention (APOP), which surveys pet parents and veterinary clinics about every two years, about 70% of parents would like to have cat weight loss and diet discussions with their vet, though only about 60% reported having these chats during visits.

This implies that more pet parents want to have these discussions and they need to be prompted more. Some veterinarians are afraid of inadvertently offending a pet parent by telling them that their cat is overweight. But on the flip side, a pet parent may think their cat’s weight is not an issue if their vet doesn’t say anything about it.

A calculator tool can be helpful to bridge this gap, as it can create a great starting point for those discussions. Instead of assuming your kitty’s weight is probably fine, or asking a generic question like “How’s the weight, doc?” The question can instead be “The online calculator I used said Kitty was about 2lb overweight. What can we do about that?”
