I am very satisfied with this Chewy company, they have everything I need for my pets and at a good price and their app is super easy to use, but today my arrived in package is in very poor condition. It doesn't matter if the box is broken, but the liquid milk was packaged together with the cat litter boxes and the milk box is broken and empty. It's good that the litter boxes are good covered with plastic or they would have been damaged too!

Maybe not all cats like milk?

I bought this for an older cat, with no teeth, who is a very fussy eater. I was hoping this would give her some extra nutrition. She wouldn’t even try it. One sniff, and she was done. I gave it to the cat who normally gets a little spoiled by getting her leftovers, and she wouldn’t have anything to do with it either. (I thought she’d eat anything. Other than this, she has.) Then I tried it on the two wilder cats we have and one of them licked it clean. So it’s edible, but maybe not desirable to all.

Yummy in My Tummy

My boy Malaki LOVES this!!! I bought one to see if he "liked" it and that would be an understatement as he would drink the whole container if I would let him. He Loves Cat-Sip so I had to purchase more for my fur baby. It's a good size container so it will last a while which I was happy about. He's quiet for a while after having his Cat-Sip milk as he's very happy and satisfied until the next time.

Not surprised

Of course, my little spoiled brat snubbed his nose at it. He was never lactose intolerant until he became elderly. He’s very relentless; he drives me insane wanting cow’s milk.

Bogart loves it!

My 12.5 year old fella demands (loudly) something tasty when we get up in the morning. I briefly warm a bit of this milk in the microwave and he laps it up happily, then goes back to bed. I go to work to support him in the manner to which he has become accustomed. Cat-Sip is hard to find anywhere except Chewy, and I'm thankful they carry it. I can buy the other brand in the purple box at the grocery store, but Bogart turns up his nose and walks away. I'm pleased to be able to give him this treat.

My cats love love love CatSip

My cats are milk addicts and I tried this out as an alternative since us was lactose free. My cats absolutely love this product! It also doesn't affect their GI tracks which is always a plus.
