I absolutely love this. Being a senior citizen myself I was always worried about my cats health (over my own health) but these drops have helped my cats a lot. MooMoo loves the flavor of this and she can't wait to have it mixed with her food!

I started using Turkey Tail on my mother and daughter cat. The difference is noticeable and the mother finally has energy to play with her daughter as well as groom her!. Turkey Tail has helped me with many issues with my 7 year old mother cat ranging from cardiac to gut issues.

Huge Difference!
First supplement that didn't stop working after 5 days. I've tried four other brands and they all failed. This one keeps going.
