I believe he meant he wouldn't feed gerbils due to the fact he wouldn't want to HAVE to list it as a gerbil eater. Not that he wouldn't disclose the info but that he wouldn't want to have to.
And yes I'd rather see mouser than gerbil eater
LOL yes that's exactly what SHE meant. I could have worded it better. If selling an ASF-only eater is hard, selling a gerbil-ony eater would be almost impossible.
