i feel bad everytime its feeding day but i know as a snake owner/lover snakes eat rodents, until they come out w/ snake kibble anyway (lol that'll NEVER happen)

do i feel as bad for a rat vs if it was my dogs or cats? no, theres no bond stronger then the love a dog & their owner shares. Cats well.. lol they are super lovey/friendly on their time. im completely happy w/ that too because when they do feel like being friendly, its SO worth it

but to throw your theory outta the water.. some super tiny chihuahuas can weigh less than some small critters.. ive seen many rabbits bigger then my 6lb chi. i had ferrets weigh more also. broke my heart when they died of old age but it still dont compare to the loss of a dog or cat or horse (can only assume this cuz i dont have any but they are my favorite animal..)

its all about the bond you share w/ your pet, not the size
