Jumbo Rats?!

[luckies4me]

Yep, no such thing as jumbo rats. I really hate when pet stores label them as such. All rats come in different sizes. Some are small and some are big. I have one boy here who is 2 pounds plus and is just a big boy, mainly because his line is bred to be big. Rats who are inbred tend to be smaller, whereas rats with more genetic diversity are larger. The smaller rats they display as small are just younger rats.

You can actually get real "jumbo" type rats. They have a more technical name that's on the tip of my tongue...Well, they usually come with health problems like diabetes and don't live very long, so most breeders discourage breeding them. I don't believe you can find one in a pet store.

I need to correct you, that's false. There is NO such thing as a jumbo rat. Yes there are certain lab strains of rats who are prone to being obese, but not larger. Also breeders don't breed any rats such as this, and it's near impossible to get ahold of these rats unless you work in a lab. I would like to know and see proof of where you heard this, and if their genetics have been tested in order to prove these rats get massive, as in LARGE, not obese. There's a big differece.

I forgot to say they are called "Zucker" rats.
