The first time I bought this I purchased in bulk. I cant seem to find that option anymore. I also note that my old cat is not as interested as before with the product. Did the recipe change?

What is the shelf life of this product unopened? Opened?
Answer by ChewyDec 02, 2017
Unopened this product has a shelf life of up to 1 year. An open container must be stored in the refrigerator up to 7 days.

What is liquid Kluyveromyces marxianis var. lactis fermentation product?
Answer by ChewySep 22, 2022
This ingredient is a yeast species that acts like a probiotic. It is commonly found in milk products to aid in gut health and immunity.

Can this product be frozen?
Answer by ChewySep 06, 2020
Small amounts of the treat may be frozen in a separate container to offer as a treat however PetAg do not recommend storing past 7 days in the fridge as well to preserve freshness.

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.

Cat loves it

I thought nothing can go wrong with cat milk until my cat refuses to go anywhere near another brand of cat milk. Better leave a 5 star for this brand to show my gratitude.

Kitties love it!

My cats love this stuff! The only problem is it often arrives deformed and hard to open and use if there are heavy things in the same shipment.

Favorite Treat

Our cats absolutely LOVE this treat! It's one of their favorites and probably the only time they are willing to share lol. It's a great alternative to regular milk, which normally upsets their stomachs. If you haven't tried it with your cats yet you definitely should!

Kitty gives 4 paws up

I have a 17 year old kitty in renal failure. I tried this because he is off/on a picky eater due to his age/condition. I also have to ensure that he stays well hydrated. He LOVES this stuff. I love the fact that it has taurine added to it.

He loves it.

My senior cat loves this stuff. I tried one carton in case he didn’t like but now I’m putting several on auto delivery because he loves it and I love it because it doesn’t make him barf. It just has him waking us up before our alarms because he can’t wait for breakfast time.

Great Product But Poor Shipping And Packing

My many cats love the PetAg CatSip Real Milk. They can have milk without the digestive side effects of regular cows milk. But Chewy uses the cartons as packing material with their heavy cat food cases, so the cartons always come crushed. Sometimes they are so crushed they leak all over the rest of the order, the box, and the floor. That makes for a very unhappy customer.
