Pasteurized or Unpasteurized Goat's Milk for cats and kittens?

I want to give them Goat's milk occasionally but the store has Pasteurized and Unpasteurized Goat's Milk. Which one is ok to feed for my cats and kittens? Please help

Wow, they sell unpasteurized milk where you live? That's cool--they definitely aren't allowed to sell raw milk in stores in the U.S. Anyway, raw milk is usually more nutritious. But there's a reason for pasteurization. . .to kill harmful germs that can make you sick. So only use raw milk if you know it's fresh and you trust the source to have handled it properly. Although I don't think cats are as susceptible to those germs as humans are.

Adult cats don't need milk. So only give it to your kitties as an occasional treat.

Yes I just said to the seller I want to buy Goat's milk and he said which one I want unpasteurized or pasteurized so I don't know what to choose yet.    I just buy unpasteurized since it is more healthier to feed my kittens? If it is unpasteurized should I give it to them like once a day? Or should it be like occasional like once or twice a week?

And also the bottle is 1 liter and they said it will only last for 5 days. If I put it in the freezer will it last longer? 

Neither your cat or your kittens need milk.  They should have clean water available at all times.

Goat's milk is generally considered fine for cats if you really want to give it to them. Freezing the milk should be fine too; we always freeze our milk bags.
However, there is no need to give your cats milk - fresh water out all the time would be much better.

I live in Colorado and Answers A+ makes raw foods as well as raw goats milk.  It does say not for human consumption but I know a few people at the pet store use it in their coffee and drink it too.  I would like for BooBoo to drink it but she eats Rad Cat and rarely drinks water.  My Pug eats raw and I mix it in with her food and she loves it.
