My CKD 21 Yrs old Bengal has greatly improved by using it, no more muscle waste and his coat is beautiful, his energy improved, i just have to use it in small amounts so he accepts his meals, he is super picky
My two like it in their wet food. In fact, I think they like the flavor and it helps them to tolerate the wet. They are finniky.
My cats have more energy and their fur is shiny and thick. They do hate the taste but their mom gives it to them everyday as I see a difference. Wish I had this with prior cats. Will always give it to them. If it could taste better they might be happier though!
You have requested my opinion after only having the vitamins for 3 days. I find myself unable to tell any difference in my fur baby in such a short time frame. I do know, she only tolerates eating her meals with Spectrin splashed on it but I don't think she especially loves the taste. Perhaps she will grow to really like it at some point; only time will tell. As for its' vitamin and mineral content - I haven't a clue if it will help her after only 3 doses. Ask again in a month or two? Meanwhile I am encouraged by the other customer reviews and hope for similar results.
