can’t say it helped can’t say it didn’t

he eats his food like normal, but I don’t see any improvement in anything or anything wrong which is why I gave it a three star I really have not much of an opinion

he eats his food like normal, but I don’t see any improvement in anything or anything wrong which is why I gave it a three star I really have not much of an opinion about this. It didn’t make his stomach upset so as long as it’s helping his immune system. That’s all I care about.

It's working

I purchased this for a cat with stomatitis because he is allergic to L-lysine and it seems to be working. He has had fewer sore mouth days than he had in the past

I purchased this for a cat with stomatitis because he is allergic to L-lysine and it seems to be working. He has had fewer sore mouth days than he had in the past and is no longer itching from the L-lysine allergy. I will purchase again.

The immune support supplement seemed to work as well as other brands of immune support I have used in the past. I currently have 3 cats on an immune support but they were not a fan of the powder even when mixing it in their wet food.

My cat Maddie seems more active

When I got the doctor Bill's pet nutrition immune support, my veterinarian had told me that my cat had some type of respiratory issue that he could not be certain

When I got the doctor Bill's pet nutrition immune support, my veterinarian had told me that my cat had some type of respiratory issue that he could not be certain of what the cause was.Maddie would have a juicy cough that would come from within her lungs. I've done tons of research and found that Dr Bill's pet nutrition feline immune support was the best option. I have been giving it to her twice a day in her food which she eats readily. I have noticed a decrease in her coughing and all out better general health. I will continue to use this product for a few more months and plan on giving an update when I have even more time to see how it performs but for now I am giving it a four star because I have seen improvement.

I have 4 cats...3 of them absolutely love this product and clean the bowl completely. My orange fella isn't fond of it, but is not a huge beef or poultry fan. It smells good and to 3 of my cats, it tastes amazing to them. I feel if they had a seafood or oceanfish flavor, my orange fella would clean his bowl too.

seems to be working on my barn kitties

I have a couple of semi-feral barn cats that I take care of, and I'm always worried about something happening to them. Since I can't touch them without trapping

I have a couple of semi-feral barn cats that I take care of, and I'm always worried about something happening to them. Since I can't touch them without trapping them first, it's hard to give them general check-overs when it seems like something is wrong. I started mixing this in with a little bit of wet food, and they both eagerly scarf it up. Since starting on it, it seems like their overall well-being has perked up a bit, so it's got to be doing them some good. Since this is relatively inexpensive, I'll probably keep them on it indefinitely, and will update my review in the future with more info.

Does What It Says On The Pouch

I have multiple FIV+ cats so I purchased this product because lactoferrin has been recommended to control inflammation in cats with FIV, and it seems to be doing

I have multiple FIV+ cats so I purchased this product because lactoferrin has been recommended to control inflammation in cats with FIV, and it seems to be doing what it claims to do. The cats are healthy, active and have good lab results when they see the vet.
