2x Blisso Advanced Cat Probiotic | Cat Probiotic for Diarrhea & Kidney Support

I have two elderly (17 years old) cats whose mother was feral. They are showing signs of aging. The male started having balance problems and getting matted hair and skin flaking on his lower back. Four months ago I began putting Blisso drops on their food in the morning. The male's skin problems have improved and they both are more energetic. Thank you very much.

Not really sure if it's helping my 15 yr. Girl or not. Couple weeks ago had to take her to the vet for throwing up. She received a nausea injection & seems ok, except not a great appetite. Overall she seems fine. Here's a recent pic of her.

My cat had diarhea bad. My vet suggested I change his food to the Royal Canin but it costs a fortune. I ordered the Blisso and changed his food to something with more protein in it that I can afford. I also started the Blisso drops at the same time so I'm not sure if it was the change in his food or the Blisso, but he doesn't have diarhea anymore. So I will probably just keep buying more and keep it in his diet.
