My 15 year old cat has arthritis and the last couple of years she has been pretty uncomfortable. My vet recommended fish oil, so I have been adding fish oil to her food for about 2 years now. The fish oil we were using, recently changed their formula and no longer seems to be intended for joint health but focuses on skin and coat instead. As a result, I found I needed to up her dose considerably for her to get any sort of relief. I decided to look for something else, and came across this product while I was searching. I looked into it, read some articles and reviews and decided it was worth a shot. I have been giving her one scoop a day, mixed with her canned food, for almost a month now. I still feel like it’s a bit early to write this review, but I have noticed a difference and wanted to share. Since she had already been on fish oil prior to this, I started out with a normal dose. The first week I didn’t notice much difference. By the end of week two, she seemed more comfortable, and since then, I feel like she has been more active. I haven’t noticed any side effects, no vomiting or diarrhea, etc. In fact, her appetite seems to have improved, if anything. The container comes with a scoop, which is very small. I was actually surprised at how small her dose would be. I’ve had to put so much fish oil in her food in the past, so I was relieved to see that she shouldn’t need much. I feel like, if you take the dose size into consideration, the price is not so bad. I recommend talking to your vet about this and giving it a try, if your pet has arthritis, or joint pain. It seems to at least be helping with her soreness.
