I had not heard about the Oxbow Senior Pellets. Thanks for the intel 🌷
(A long time ago) our vet had recommended that we give our senior rabbit, Eeyore, alfalfa hay for extra protein. And another time, towards the end, our vet told us to let our Poppy Bunny eat what ever she liked and suggested Cheerios. And then when Butternut was very ill we were told to feed him beet pulp. I could only get it in huge bags from the local Tractor Supply.
So many sweet bunnies. Stay strong, Casper!
