My cat Starr is currently on primal defense powder 1 scoop per day and GI Encap Pills 1 pill per day as well as feline vitamins and he's also still on 5mg of prednisolone which I hope to be able to wean him off of soon. So far he's doing very well. I just mix half of the herbal supplements in his food in the morning and the other half in his food in the evening. I noticed an improvement in just 2 days even though my holistic vet said it might take 7-10 days. I hope that Kirk will be able to feel better soon. Good luck.
