Helping my two senior cats
Important to take with food if your cat has a sensitive stomach to avoid gastric upset. I always give immediately after a small meal. Both of my senior cats who are stage 3 CRF have much improved bloodwork since being on this formula. I use a pill popper with a silicone tip and coat it with butter. The capsule is sized for cats. They get a small treat afterwards and now look forward to it. My vet is impressed with the effectiveness of the formula. No stomach upset. I’ve seen improvement in energy levels and coat health also. Update: I can’t believe my playful bouncy 15 year old cat was once diagnosed with stage 3 CRF. After a year on this formula her bloodwork is perfectly normal. She also gets her sub-q fluids but there was no dramatic improvement until she started on this formula a year ago. Her daughter is also doing great despite just undergoing treatment for hyperthyroidism which is hard on the kidneys. She has gained back all her lost weight.

Easy to administer, quality supplement
Arrived quickly. Like that it has NASC seal for quality. For small, elderly cat trying half capsule 2x daily. Capsules are small, but can easily twist open to sprinkle on wet food. Mixes in well, cat gobbles it up. Will increase to full capsule and see how it goes. Looked at a number of products for renal help for cats, chose this for the variety of ingredients to aid in renal care and the ability to administer easily. Will take time to see its effectiveness, hence only four stars at this time, but feel it will help over time.

It may help.
Capsules are a pain in the ass to open. But my cat is drinking less water. So we will see.

Prevention is the Key
I sometimes wonder if there are enough good ingredients in the food we give our cats. I like the idea of this anti-inflammatory and kidney support for cats may benefit their health. We as "hoomans" love to keep our pets as healthy as we can, and I was happy when I saw this product. The instructions of dosage are well explained, and the powder comes with a small handled scoop, that you can sprinkle in your cats food. I guess in the long run we may never know if these supplements are actually helping, but I feel better in trying. By providing your cat with the extra RX Vitamins as illness prevention, we may be helping with their maintenance of a healthy immune system. Also, I feel that this is a creditable company, that provides a NASC Quality Seal; which identifies products from companies that are committed to quality, vigilance, and continuous improvement to promote the well-being of companion animals and horses.

Good product
Over the past two years, my awareness has increased that kitty's developing kidney disease is significantly on the rise (along with dogs). While Vine will not allow me to list the primary causes in this review that I've deeply researched about this subject, I highly recommend doing some research to discover them for yourself, you will be very surprised at what they are. In my opinion, doing so may greatly help your pets live a healthier and longer life. At any rate, this Rx Vitamins Renal Feline product may be quite helpful in helping prevent the onset of kidney disease due to its clean ingredients and anti-inflammatory properties. I find it best to simply add the designated amount for your kitty to wet food and mix it in. Most of them will ingest it without any issues. However, as you know, some kitties will turn their noses up and walk away...

My kitty is feeling good, happy pet parent
Wow. All I can say is wow. I got this for my kitty because she has been having some urinary issues: not too much output volume. Since giving her this supplement, she is making an extreme turnaround. I am super excited! I am really quite grateful for this. The caps are really tiny, so I can open them up and pour them into her daily Tbsp of pumpkin. She takes it for me, although I don't know if she's extremely thrilled with the flavor. It’s okay, I’m happy with her feeling better. Five stars.

TINY capsules!!
I just started giving these to my older cat as I'm worried about her kidneys as she ages. Let me say this: I have never seen such tiny capsules in my life. This is an issue because it's one capsule for a ten-pound cat, and my kitty MIGHT weigh half that. So I have to open the capsule and put half of it on her food, and that's a difficult task with those tiny capsules. I put the vitamin on her wet food, and she eats it right down without hesitation, so it doesn't taste bad to hr or flavor the food too much.
