Good to know about the guinea pigs. Guess i'll skip those then. There is a place by me called Rodents Plus which says they feed all their feeders high quality mazuri food with filtered water etc so i'll probably give them a try. They also got 1-1.4 lb rabbits for $3.49 which is even better. Figure i'll do a rabbit once a month for my big gal so next month, i'll probably buy another from the local place and weigh it when I get home so I know how large I need in weight as the first one I bought seems to be the perfect size for her but like I said, I forgot to weigh it lol. And with Rodent Plus being close to me, I can save on shipping too and just pick up my order This works great for my boas but i'm sure my BP will give me problems haha. If she isn't tearing her cage apart at night or trying to tip the water bowl, she is going through her hunger strike lol.
