Fat Cats Cost Fat Stacks

I’m not good at estimating things, but I’d say about 90% of the pets I see are overweight to obese. Owners don’t like to hear this, though. If they could just have a big eyed, furry thing to pet and feed forever, that would be their ideal life. The animal wants the food, it makes them “happy” and if baby is happy, owner is happy, but the animal doesn’t seem to really ENJOY the food typically and just wolfs it down and looks for more like “I can’t believe that’s all you’re going to give me” and the big eyes instill guilt, we feed, feel happy, then guilt for not giving more, and so the cycle continues. Unfortunately as they get older, or even some at a much younger age, the extra weight can cause so many more problems.

Dan, the office cat: OBESE 19.5lb – should be about 12lb

People tend to judge how much their pet should weigh based on their breed (or perceived breed) and their parents’ sizes. I often hear “well, how big should he be for his breed?” or “well, his daddy was HUGE – with a head *THIS* big and was 195lb!!” There are a few problems with this theory. 1: every breed has a wide range of what can be normal (height, thickness, etc) , 2: every individual gets different genetics and may not end up as large as their parents (or could be larger) – My parents were both 5’11” and I ended up 5’8″. 3: just because the parent was 195lb, that doesn’t tell me if that parent was an ideal body condition and not also obese.

In general, you should be able to feel your pet’s ribs, but not see them. So, especially with those super fluffy critters, you’ll have to put your hands on them to decide if they’re too fat/skinny. Have them stand up, then run your fingers down their ribs. You should be able to easily feel the ribs without pressing, but not feel any depressions between them, like the back of your hand. If you have to push through flesh to feel the bones like you would on your wrist, your pet needs to lose weight. If you can feel spaces between their ribs like your fingers, your pet needs to gain weight.

Here’s an equation to figure out how much your pet needs to eat in a day (not just their pet food, but you have to include EVERY calorie that goes in their mouths – food dropped, just a little snack while cooking, kids feeding them, treats every time they go outside and use the bathroom, the cat’s food when you leave it out for them to steal, etc, etc). Remember, a 100 calorie snack for an adult human could be 50% of a small animal’s daily needs. So, even just a little bite for you could be enormous for our pets. And don’t be fooled by the pet who is ALWAYS hungry. Unlike us, they have no concept of “being healthy” other than “EAT WHEN YOU CAN BECAUSE YOU NEVER KNOW WHEN THERE WILL BE FOOD AGAIN!!!!” Remember, a dog/cat has about the intelligence of a three year old child, so we have to be their brains and think of their health for them.

Catina is a small framed cat. She weighs about 8.5lb but should be about 6lb.

Daily calorie needs for your pet = 70 x (Ideal body weight in kg)^0.75

*********DOG FOOD BAGS LIE!!!!! DON’T FOLLOW THOSE INSTRUCTIONS!!!!!**************

** weight in lb/2.2 = weight in kg

** Ideal weight = body weight – (body weight x %overweight)

  • with % overweight = anywhere from 10-40% overweight (ask your vet)
  • So, 42lb beagle that is OBESE is about 40% over weight, so ideal body weight = 42 – (42×0.4) = 25.2lb
  • So, a 42lb beagle that should only weight 25lbs, 25/2.2 = 11.4kg
  • calories = 70 x (11.4kg)^0.75 = 70(6.2) = 434 calories per day
  • To make it a little easier for you, here’s a chart (This is for ADULT animals, not growing/lactating/pregnant – Also, this is IDEAL weight, not their current weight if they’re obese)
  • Talk to your vet to get your pet’s ideal weight
Popcorn is a perfect weight – she’s an average frame cat and weighs about 9lb

Our pets do not live very long (10-15 years for most dogs; 15-20 years for most cats), so giving them the healthiest lifestyle keeps them happier for those years. Arthritis and diabetes are common sequelae to being overweight as well and breathing difficulty in the short squat dogs like French and English bulldogs. Osteoarthritis leads to many many euthanasias and dogs that are overweight are GOING to have more mobility issues and will start getting them much earlier in their lives. Mobility issue leads to being unable to get up from laying down, walk over hard floors, navigate stairs – making owners have to carry dogs to go outside to the bathroom (think apartment living), bed sores, other injuries from slipping and falling, infections around skin folds around rectum, penis, vulva. Diabetes treatment requires twice daily insulin injections, multiple vet visits to get insulin regulated, regimented note taking and nursing care, and, of course, more money. (Just think of all the money you could have saved by NOT feeding your dog all those extra treats AND diabetes/arthritis therapy!)

This hippo is a bit on the thin side…

Cats that are overweight will start with arthritis, but you may not see it (see my last blog on pet pain) until you start noticing your cat urinating or defecating outside the litterbox. Inappropriate urinating and defecating is one of the leading causes of cat euthanasia – and it all could just be because it hurts to walk into the litterbox or get into position to poop. Obese cats will also develop diabetes ($$$$), stop being able to groom themselves, leading to mats in the hair, grumpy cats, and infections around their rear from feces and urine sitting on their skin.

The most loving and money saving thing you can do for your pets is to stay ahead of the problems – flea/tick/heartworm preventative, vaccines, and keeping them at a healthy weight are the absolute minimum for giving your pet the healthiest and longest life you can. You may feel like they love you more if you feed them, but they don’t really associate food with love. Over feeding them can border on cruelty and abuse. You are their caretaker. You control what they eat – 100% – you can show your love more than anything in the world by keeping them at a healthy weight. You can do this!

Happy healthy dog!

  1. Thank you for sharing this with us. This is good information that pet owners need to hear and read. Keep up the good work.

  2. Weirdly, I’ve been very lucky with both my terrier mutts. I live alone so I ALWAYS have water and a full food dish in their crates. Neither dog was a constant eater, usually eating the most around supper time. I once left my Bichon in his crate on Saturday morning, had a medical emergency and didn’t make it home until Monday afternoon. A friend made one quick trip to let him potty and he did not eat all his food nor dirty his crate. Of course, I expected a mess but he held it. I seriously don’t know his thought process but I think he equated cause and effect. I know it’s unusual but he has learned he always has food and water and he doesn’t overeat. Weird, huh?

  3. Dr. Emily you explained appropriate weight management to a T. It is extremely sad to see so many pets overweight because it wasn’t their fault. They can’t eat it if we don’t give it. I have 2 beagle girls and being chow hounds I fight weight constantly with one. My 12” is 22 pounds. Muscular but still 22 and she should be 17-20. My 15” is at 28 and looks very healthy. I have switched from bones as rats to frozen greens beans. Darn near zero calories and tons of fiber. Thanks again for sharing your insight to a very touchy subject. I hope you and the family are well.

    Kind regards,

  4. Thank you for your posts, Dr. Emily. I always look forward to them.

    Ginger is 19 and has kidney disease and hypothyroid (after i131). She was 11 pounds for a few years, at her peak. Since her thyroid issues began 7 years ago (and she got the cure), she has very very slowly gone down to her current 9.5 pounds. It is a struggle some days to get her to eat enough (she’s always been a picky eater), but we get it done, sometimes with antinausea meds and appetite stimulants.
    She’s a larger “Main Coonish” long haired calico.
    My vet says she is a great weight for her age.

  5. Thanks for the information. I enjoy your blogs and the helpful insight you provide.

  6. Yeah when I was a teenage I thought my friends cat that was like at least 20lbs so cool.

  7. Thank you for the timely reminder. For the past 50 teats that we have had cats only Pickles was over weight. She passed about 16 mis ago from feline IBS. She was 16 years old and had often had far too many hairballs nearly her whole life. The diagnosis finally came about six mos before she died. By that time getting the liquid medication in her was difficult—baby food chicken was the only way. But she kept her girly kitty waistline until the last six mos. She was well loved and our vet worked with us to try and keep her healthy.💕💕

  8. Very informative, thanks, Dr. Emily.

    So what’s the plan for Dan, the clinic cat?

  9. Thank you so much! After reading your post I’m putting my Rottie Ikaika on a diet. 3 1/2 cups a day.
