Actually I’ve owned several, full size, dwarf, different varieties of Lop’s. Give it time. Thus why I asked if it was a dwarf rabbit, as many people get cute little bunnies (especially around Easter time) that grow into very large rabbits that become major chores to take care of. Imagine that old guinea pig 4-8 times in size. Also, not once did I suggest guinea pigs aren’t just as bad if not worse than rabbits, just not as big as most rabbits.
