Good stuff

My vet recommended this years ago when I feared I brought home a respiratory disease from a shelter where I volunteered. I sprinkle a little of this on Frankie's wet food twice a day. It keeps sniffles and allergies away and is supposed to be good for ocular health. He is sixteen and has the bloodwork of a kitten.

Orange cat happier

So far it seems to be helping my 1 year old's minor, but chronic, respiratory issues. Lysine was vet recommended and I chose this to try. Happy so far.

White powder no smell or taste, respiratory issues

Big bottle of a white powder that cats will not detect in wet food. My rescued cats with respiratory issues, gets it three times a week and never found out I hid it in his wet smelly food. Yes, cat feels way better with this health support. I use the same bottle for outdoor cats also, has a Great price.
