Is this the same thing as the cell advanced 880 just a smaller dose? the 880 has a different description.
Answer by ChewyJan 18, 2018
The VetriScience Cell Advance 440 Immune Health Capsules does have a lower dosage of active ingredient per capsule and is recommended for use in small dogs and cats. The VetriScience Cell Advance 880 Immune Health Capsules has higher levels of active ingredient per capsule but is only recommended for use in dogs, not cats.

Can this help my cats with food allergies? Right now I have them on probiotics, and it is helping but they need a little extra help. Every now and then they still itch. Does this need to be refrigerated?
Answer by ChewyOct 25, 2018
We recommend consulting a veterinarian before adding supplements to your pet's daily diet. Each pet is unique so we encourage you to seek professional guidance to select the best products along with their current health. This supplement should be stored in a cool, dry place.

My dog weighs 110 lbs and my cat 22 lbs. 13 pills per day?? The bottle would last me 4 days?
Answer by ChewyDec 29, 2017
The Capsules are formulated specifically for small dogs and cats under 30 pounds.

can it be put in a syringe? My cat won't eat it on his food or mixed in food!!!!!!
Answer by ChewyApr 05, 2022
The Cell Advance capsules can be opened and mixed with water. Warm/hot water should not be used, room temp is fine.

Did not help

My cat has herpes virus and I hoped this would help her. Unfortunately the product did not improve the condition.

Excellent immune assistance!

My 19 yr old cat has responded so well to this addition to his food! I cut open a capsule (since he is less than 10 lbs) and sprinkle the powder on his food. He has more energy and his mobility has improved. Thank you!

Won’t take them and won’t eat if they are in plate

My pup won’t touch her food if these are sprinkled on or hidden inside of. She must smell them in there. Refuses to eat them- wish she liked them.

Won't take them

My senior cats will not eat food that have had the supplement put on it. The capsules are too large to give whole.

helps FIV+ cat

This product really seems to be helping my FIV+ cat. I recently brought in a feral cat and initially he seemed to have trouble breathing and was very mucus, running eyes, etc. These symptoms are hardly noticeable now and he seems much healthier!

Seems to be working

I bought this for my FIV+ cat because he was looking poorly. His eyes have stopped weeping, and he looks visibly healthier. I just started giving it to my 14 year old cat to see if it helps her as well.

Kitty seems to tolerate

I have a small cat with fiv and kidney failure I give her 1/2 a pill sprinkled in food and she seems to tolerate it as with some other’s she won’t Eat it if the vitamin is in there. As to if it’s helping her or not I’m not sure but definitely has some good ingredients for cheap.

immune health

Important if you have an indoor animal that goes outdoors, allergies can reek havoc on the immune system, excessive paw licking has been Brutus' main issue. Pills seem to help.

I use this along with lysine for my rescue kitty that has chronic respiratory issues. Helps keep him clear.
