Ditto what SR said.
I feed bp to my old man, the only one of the dozen here that get it. He will be 31 here shortly and has very few teeth left. He has a hard time with hay - he does get chopped quality leafy hay but he can't maintain weight these days without the beet pulp. The fiber aspect of it is really important in his diet. He gets it fed in a mash with senior feed and alfalfa pellets.
Life is like a camera. Focus on what's important, Capture the good times, Develop from the negatives and if things don't work out, Take another shot.
