Yucca Supporting Aisling

"Our kitty is doing so well with the Yucca supplement! No more vomiting. Vet is going to gradually reduce her [pharmaceutical name removed] meds. She seems to be having some joint pain. What do you recommend for that? She is a rescue, so true age unknown. But probably at least 15 yrs old. She weighs 5.5 lbs on a good day…. She has recheck next week…may be regaining a bit of weight as she is no longer vomiting, but has never been a big eater. Only 8 lbs at her heaviest. We are so happy with the improvement. I realize that because of her age it may only be temporary, but at least now she is comfortable and I feel as if I have tried everything. Thank you for your help!!"- Anna
