@mcc i might be wrong about this but isn't it actually even the other way round, with rats that were bred to be cute and pet-like having a higher cancer risk than lab rats due to being over-bread?

bc when me and my relatives had rats that were bread to be kept as pets they all died rlly quickly, but then we got lab rats instead (as pets, i mean) and they lived for wayy longer

There's still a lot of factors that have to be accounted for.

For example, the lab rats are bred and designed to be as healthy as possible, while the pet rats are bred to simply survive long enough for a child to grow bored of them.

And then fed to the pet snake.

sprague dawley rats are used for cancer research cause they generally get cancer after like 2 or 3 years. So you can faster results on how cancerous something is if the rats get tumors within like 6 months

Fun fact: An anti GMO group used this to spread fud about gmos giving you cancer by showing off enormous tumors in sprague dawley rats. Except the rats in the study were years old

@skyeye @kinyutaka @phseiff @mcc IIRC a lot of pet rats are descendents of lab rats and this is why they too are predisposed to growing tumors. Also the "look at all this cancer in the cancer rats" study I'm aware of was about glyphosate/Roundup: whether or not it can cause cancer, the most widely popularized study (which had photographs of grotesque tumors) was the result of keeping the rats alive well past the point they naturally develop severe tumors for shock value.
