moff, When i was at the vet's spay clinic last Friday , she recommended Nutra-Cal for Tiger, after reading my brief write-up on her. I didn't realize the benefits from such a nutritional suppliment. I think I left her with the impression that I didn't care if tiger was feeling up to par or not. Sometimes I get "saturated" with information and do not respond as I should. However, after thinking about purchasing a tube of Nutra-Cal, I returned to the vet's office yesterday, and purchased some. I am glad I did, because it has helped Tiger with her energy level, stomach and digestion problems.
