Baby rabbits need the protein and calcium inalfalfa. You can switch her to timothy pellets at about 6months. You can feed either alfalfa or timothy hay at thatage. I free fed timothy hay with some alfalfa as a treat withMocha.
You can try introducing them now, but be aware that Pristine's attitudewill probably receive a major adjustment when she becomes ateenager. If they fight a bit, it would probably be best towait until after she is spayed. If they get along just fine,then let them play together and just watch for any hormonal issues.
