Can confirm. I used to keep feeder rats and lab rats. They do not mix. The dark colored feeder rats would attack the White lab rats if placed in the same enclosure.

"Rats" caused the black plague. This is actually where the historical reference to jews being rats comes from. Jews said oy vey it was rats, so everyone started calling them rats.
Rats are racist.
