    My cat has polyarthritis he’s about 16. I am giving him a combo of vitamin c. He has no poo problem eating it with his wet food. He use to lay down by his bowl waitting for his food. I’m thinking this is because he was in too much pain to sit. Now I noticed he sits by his food while I’m preparing his food. He also tries to do things beyond what his body is capable of like jump from my bed to the dresser. Doesn’t matter if he falls he’ll do it again. I’m not sure if this is a good thing but if it causes him pain I’m sure he wouldn’t try that again.

    I’m not sure yet as my fairly new cat is only a year last July but we will see. He has plenty of energy

    Seems to be just what the doc ordered. Great relief regarding dry, itchy skin. He really loves the flavor. An excellent product that I’ll use again.

    I have a cat diagnosed with possible pancreatitis. She did not tolerate the steroids well, and i was happy to find this product. Only two weeks in, but she has no problem with the product, is eating her food and I am cautiously optimistic.

    So far….It’s great that my cat is eating the food I put the product into. Too early to tell if it has any effect on his various issues….biting his back fur, periodic throwup, scooting.

    I got CATalyst for my 16 year old cat because he was getting lethargic and not himself. It is still too early, but he is eating and moving around a little more. Hoping it will continue to help him

    I absolutely love the 2 crazy cat ladies and I’m hoping this product works for my orange fur baby, Ichigo. He’s had greasy/separated fur that the vet didn’t seem too concerned about, so I wanted to try something new. I’ve been struggling to get him to eat it, though. He does that thing cats do when they sense medicine 🤣 He’ll only eat it if I put fortiflora on it, but I’ll be back with an update once he consumes it consistently!!

    My Sylvester has allergies but Vet allergy meds keep him sleepy and cranky! Only been using this for a week and already he acts like he feels better…more social. I will continue using this product via syringe. I am very happy my beautiful boy seems to feel better!! Thanks Cat Ladies!!!

    I can’t comment as to effectiveness yet. I have only been using this for maybe a week. So far, no difference in my cats behavior, but I know it takes a bit for anything to get in their system and start working. I figure it’s good for her regardless. My cat has feline hyperesthesia and shows OCD symptoms. She hasn’t bit herself to hurt yet, only screams and nips at her tail. Service was great, fast delivery.
