Oh, HuggLES AND HuggLES you! I don't know what to say or do. I mean, everyone says if they are eating and appear happy, let them be. Maybe contact a bunny group, and ask if anyone knows of something that would help?
Oh, first my LJ friend's birdie, and now possibly bunbun. *sniffs* My Red Dwarf will take good care of him, if you have to let him go. He adored animals, and they adored him. Silly old dog.
