A study by the British veterinary charity PDSA (People’s Dispensary for Sick Animals) has shown that over the past 5 years, dental procedures done by PetAid hospitals on rabbits has quadrupled. Many of these dental issues stem from poor diet.
I’m not sure if the increase in procedures is due to more rabbits failing in health or just that more people are actually noticing their rabbits need veterinary assistance. Either way, it should be noted that rabbits’ diet should consist mostly of hay.
