Yeah, but breeding for me to make money was something that came later. I wanted to make REL's just because I wanted one. I was doing behavioral "experiments" with spider bps. They taught me a lot about BP's in general. At some point I was breeding just to break even on my hobby. Rats alone cost me more a month than most car payments. Now breeding makes me a little extra cash. I am pretty much at my limit with the number of animals I have at this time at least until I retire.
I don't spot clean. I am on paper. It gets thrown away and everything is disinfected every time.
