My local SPCA currently has two guinea pigs that have been there for a few months now. I have been trying my best to help them in any way I can. I just found out that they have been giving the pigs different pellets brands of pellets very often, so I decided I'm going to try to buy them a big bag if pellets and buy them a new one ever month so they can stop hurting their poor stomachs with changing up their food. Now, being a poor college student, I can't afford to give them the best of the best pellets like I do my current pigs. So, I was wondering if anyone knew a cheap, but still good, brand of pellets that I could buy from Petco or petsmart. Also, any ideas of cheap things I could get/make for them to go with this gift basket I am giving them.
