HAHA no special secret for Flash he's been thru alot with his previous owner's. His first owner just used him for business purposes and wasn't treated like a pet to educate children, and his next owner loved him but didn't take very good care of him. When I brought him home he went to the vet asap to check him. He still has problems with his teeth and now a cold he can't shake.
I feed him Oxbow pellets, he doesn't eat hay even tho I give it to him everyday. Last year he stopped eating any veggies. I've increased his pellets to a half a cup or more and he gets banana, apple, pear, or watermelon as a treat. He's free run and gets alot of exercise and alot of love. He has a will and he's a survivor and my vet did a wonderful job taking care of him with his problems.
As Patti mentioned I submitted his paperwork for Guiness Book of Records as the Oldest Living Rabbit. They said it takes 6 weeks so we shall see, cross paws.
