Good for older cats (& all cats)

I ordered this for my almost 16 year old cat Sassy who had developed heart arrhythmia. I had read many of the reviews from cat parents whose cats had heart problems

I ordered this for my almost 16 year old cat Sassy who had developed heart arrhythmia. I had read many of the reviews from cat parents whose cats had heart problems and it appeared to help some of them. Turns out Sassy was going into congestive heart failure. Unfortunately, I was probably too late, because Sassy crossed the Rainbow Bridge about a month later. But I’ve continued to add this to food of all my cats, from the 2 and 4 year olds to the 14, almost 16, and 18 year olds. Many senior cat foods add carnitine, and some increase the percentage of taurine a bit, but these ingredients are important for heart health, especially taurine, and some foods add the barest of minimum amounts of taurine. I still have Sassy’s twin brother Rowdy, who will be 16 in one week. He is active and vibrant. If this additive can help these senior cats stay healthy, and keep my young ones from going into heart failure some day, it’s worth it. I will continue to supplement their food. And the cats must like the salmon flavor. No one has rejected any of their usual foods with this added.

I purchased this product for my aging cat. He is 13 and noticeably slowing down. Within 2 weeks, his energy levels were up, his coat had become softer. He acts like he feels better. If it will help keep him happier & healthier in his elder years I will buy it for him. Great product! Thanks!

My Rolo is 10+. I give him supplements to support his joints and mobility and as soon as I added this to dinner day one, he cleaned the bowl and was zooming around the house for a couple laps like he was getting the old Corvette out of the garage lol We both approve!

I bought this for my cat and unfortunately he couldn't eat it due to the big size. I opened it and poured it over his food but that was not appetizing. :( for a dog this may be a decent size but for a cat its a tad too big.

Good ingredients for heart health

The capsules are big so I mixed it into her favorite treat and she woukdnt touch it. So now Im spending time splitting each capsule so I can direct pill her twice

The capsules are big so I mixed it into her favorite treat and she woukdnt touch it. So now Im spending time splitting each capsule so I can direct pill her twice a day. It would be great if they made cat- specific ones in smaller capsules!

Chihuahua has a murmur

Purchased these as support to a Chihuahua and a senior Corgi mix that have heart murmurs. They seem to help.

Loving it so far!

We've been using this product for about a week now, I have an 8 year old dog who had a "bit" of an enlarged heart for unknown reasons at her last check up, no murmur

We've been using this product for about a week now, I have an 8 year old dog who had a "bit" of an enlarged heart for unknown reasons at her last check up, no murmur though... Figured it would be best to get ahead of any issues with a supplement from a brand that I already love and trust! So far, no ill side affects, she takes the pills easily and I am excited to see improvement as we go!

I bought this for my cat with advanced heart disease and it really has improved his quality of life. Stupidly, I ran out last month and waited a couple weeks to buy more. Big mistake. As soon as I got another bottle and started giving it to him again, his symptoms calmed back down and he’s back to thriving. This supplement has been a miracle for us. I’ll never run out again!

At the yearly check-up last year the vet said she's hearing a slight heart murmur. So instead doing tests and procedures I added this cardiac support to my dog's food daily. I open the capsules and sprinkle it on his food. At the recent check-up the vet did not hear any murmur, instead she said the heart sounds good and normal. I recommend this supplement - it works!

Easy to sprinkle on her food and mix in

It may be a great product but she won’t eat very much of the wet food I put it on. She knows it’s there.
