I was kind of notorious when I was living in Des Moines for buying up all the guinea pigs and such that went on sale at the local pet shops when the food I bred for my 'babies' was getting thin. The pet shops thought they were pets. I thought different. Thankfully I HATE mice and rats and love to raise them for food. Its the freakin crickets that stink up my critter room the most though, I have to have a ton of them for the arachnids and the geckos. The geckos are fattening up their tails this time of year and are eating the ***** out of them right now.
