My cat loves it and I've read very good things. Some of the cat foods being marketed as healthy still contain the same unhealthy ingredients you always find, so beware -- there are not as stringent rules regarding false advertising when it comes to cat food. This one has received very good ratings from vets and others who compare the different cat food options out there.
My cat noticeably more energy as well, which I wasn't expecting since she's still fairly young and energetic. This food is very different from your average dry food though, it's like little pieces of jerky instead of hard kibble. So mixing it in with your regular cat food until they are used to it is a good idea.
We LOVE this product for our cats - it changed our little one almost overnight - AMAZING stuff and worth every dime!!!! But lo and behold you are out of stock again!!!????? So frustrating to find something that you have been looking for to work for your pet and bam! - its out of stock. Well this is how we find other resources guys - if you don't have it - there is no alternative to it so you send us away to other sites that do carry it. We would love to order from you more consistently but if you are not in stock - sorry our loyalty is to our pets and us 1st. Please RESTOCK again soon - thanks!
