well, my bunnies teeth became overgrown yet again, even with following the doctors advice and all of that. well, rather than face a 150 dollar vet bill to have him knocked out and the teeth trimmed, we spent 40 bucks on a dremel tool set and did it ourselves. he didnt even flinch. we had him lay on his back for the procedure and it took maybe 5 minutes for the top and 5 for the bottom. he is a very happy bunny now!
