Furthermore carbohydrate calories are preferred to fat calories to meet their energy needs. Many plants concentrate minerals therefore there is not a big risk that rabbits fed a varied diet including lots of vegetables would develop deficiencies. Pellets are a good source for minerals. Dangers Excess minerals can be toxic, however, this should not be a concern with most minerals. The one exception is calcium.
Rabbits metabolize calcium very differently from other animals.
The calcium binds with other things in the urine and forms solids. In some rabbits the solids stay in the bladder and can cause problems. Reducing the intake of calcium may help prevent bladder sludge accumulation, however, care should be taken when reducing dietary calcium. Rabbits who are being syringe fed should have pellets or a mineral supplement added into the daily feedings to meet the mineral requirement.
