Okay first off I should tell you Penny has always been very picky from the start. She's about 4 months old now. I started her off on oxbow pellets (the ones for young rabbits) she ate those for about 2 weeks then all of the sudden stopped. My youngest sister has two guinea pigs and she was nosing around in their food one day so I decided maybe she will eat that. She did. Today I just bought her some kaytee Timothy complete and she just loves it. I know kaytee is not the best brand. I was just trying things out to see if she would even eat something that is timothu based. I know young rabbits are supposed to have pellets that are alfalfa based for 6 months because alfalfa is high in calcium. Is there any harm in feeding her adult rabbit food that is Timothy based? Any suggestions or thoughts are helpful.
