I wasn't talking about furred animals at all and never did I mention I have the same thought process when it comes to them, I have owned many cats and dogs in my life of not only different sizes but different weights and even thought two cats could be the same weight they each handled it differently. I find it very easy to tell and correct when my furred pets are over or under and most of the time as long as like I said animals are given the proper amount of attention and exercise weight shouldn't be much of a problem. Just like humans animals have different body sizes and deal with the weight different. My male cat just visited the vet, he is indoors and a very muscular male, his is 14 pounds and has his food out all the time, I don't personally believe in keeping an animal on a schedule. He could stand to lose a pound or two but that doesn't mean i'm going to put him on a diet. You asked about dragons, I answered about dragons, I don't like how you assumed that transferred over to my other animals.
Also I wanted to add before you think to suggest my cat is over weight the vet agreed he is perfectly healthy, he is an adult orange/tiger male and from my experiences orange cats are big cats. I don't attribute the same signs (belly dragging/trouble lifting their own weight/lazy) to mammals and I find It is easy to tell when a mammal is over weight and i'm sorry you deal with people who have a problem hearing their pets are over weight but you shouldn't assume that because someone feels a certain way about one type of animals diet it is the same all around, what is attributed to Thil is not the same for my furred pets or my snake, and same for the snake.
