Not Healthy

I haven't used this product but reviewing the ingredients, the calcium citrate isn't good for animals or people.

It Doesn't Taste Great, But It Works!

I have two cats, one 13 and one 2; I got this because I wanted to include a multivitamin for my senior and I figured it would be good to start my young guy on a good routine. Neither of them particularly enjoyed this on their dry food. They'd eat it, but they would take forever to the point of ultimately not meeting their daily intake, and my old man would complain to me all day long. I mixed it into wet food, which is better for them anyway, and they don't even notice! I do wish a scooper could have been included, but one of my husband's tiny pre-workout scoops was perfect. Regardless of the annoyances, I'm still going to buy it until I no longer can, because it really helped give my little old man a boost. He's much more alert, he seems to sleep more soundly (since he now spends ALL night hogging my pillow instead of just part), and I even watched him pounce on a dustbunny the other day - something I haven't seen in years! That pounce solidified my loyalty to this product!

Picky eater approves

My 12 year old rescue kitty doesn’t mind it sprinkled on her wet food which is rare! She’s lost some weight but otherwise healthy since last year so hopefully this is helpful for her retaining more nutrients and gain some healthy weight back.

Doesn't work if they won't eat it

I purchased this for a kitty that is NOT a picky eater at all and always licks the dish clean when I feed him wet food. I received this today and decided to start with 1/8th of a teaspoon mixed in his evening wet food. He started to eat it and then flatly refused to finish his food mixed with this vitamin powder. Tried to get the other cats in the house to eat the rest before I threw it out but no takers. I would not recommend this product.

Very Good Supplement

My cats have all shown improvement in overall health since giving them this supplement. The ones adopted from a shelter originally were dull-coated kittens with the general minor health issues common to that sort of situation. Shortly after beginning this supplement, their coats became shinier and felt softer. They seem healthier overall. Now, a year after beginning this daily supplement, my cats are all still healthy. The powder dissolves easily in canned food portions, and none of my cats have seemed to notice.

helpful supplement

Since the supply of cat food had disappeared, I've had to blend my own. I add this to the wet paste and the cats don't seem to mind.

Cat loves it

I don’t know if it is making him any healthier, but I do know my picky cat eats every drop of his food when I put this on it. He loves it. He is a healthy cat, maybe this will keep him this way.

Excellent Vit Combo!

My middle-aged rescue cat Abby lost her excess weight, but was then diagnosed with Kidney failure and borderline diabetes. :-( The Rx diets and meds made her worse; She lost a lot of muscle, could no longer meow, was often dehydrated, and could barely walk with her hind legs. My last 2 rescue cats had died from kidney failure in middle age within months of diagnosis, despite my always giving them a quality 'all-natural' dry cat food, and occasional canned food. My son noticed Abby had almost stopped eating the dry food, and I noticed she often threw it up when she did eat it. Hence the weight loss. So she switched herself to a 'Paleo' diet of 100% canned food. My Vet and I knew she probably wasn't going to last much longer, and decided quality of life was more important. So I followed cues from her. Having bad kidneys and bum legs myself from MANY surgeries (thus anesthesia & many Rx meds) after an accident, I had been trying to reverse it all for years. The latest research ties chronic organ inflammation issues (and many cancers) in humans to a fatigued immune system, the HHV virus and the toxins it excretes. To excrete them, the toxins first must be in those organs for the virus to absorb them. So a very 'clean' diet is a must. Assuming that FHV is behind it all (as various strains of HHV is in all humans), I added some Lysine (an anti-viral), extra Vit C powder (another anti-viral), adenosylcobalamin form of B-12 (for nerve repair), and aluminum-free Epakitin Phosphate binder to the 'Rx Essentials for Cats' excellent vitamin base. I mix 1/2 scoop in (1/2) 5oz can of cat food a.m. and p.m. Also always keep an additional fresh bowl of water next to her bed, and she taught herself to drink regularly, so no more subQ IVs. Abby is now 14-ish, diagnosed 4 years ago, and switched to all-organic low-carb low-phosphorus high-quality protein wet food (mostly Organix turkey flavor)+ added Vitamins + fish oil 3 years ago. Also ((carcinogenic) mineral-oil-free) Nutri•Vet hairball remedy for any constipation issues, after extra fiber did not work. Abby-cat naps a lot, is getting deaf, naturally eats only a little at a time, but Often (which is great for managing diabetes!). She still struggles to jump up on the couch, but walks fine, does not seem to be in pain, stays hydrated, pees a more normal amount, and seems to get a little bit better each year. They say one cannot recover from kidney disease, but Abby-cat gives me hope!
