@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
@phseiff @mcc
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.
