I HIGHLY reccoment a small bunny or rabbit. They are wonderfull pets and are fun to watch grow up. I have a flemish giant rabbit, one of the largest species. she is longer than 2 feet.
She Does not bite but SHE HAS MONSTER CLAWS and scratches by accident!
MOst people have smaller rabbits and Are much easyer to take care of. They do live a long time for a rodent.
However, it is hard to find a good vet for rabbits, Not many people specalize in them because not as amny people have them as cats and dogs.
