Cleaning Brand Socks

I looked in the memories but no luck ;3;

So, I accidentally left my AntP (Black) socks at my friend's house.

Unfortunately, she has 4 cats, all of whom love to sit in clothes and laundry... ugh (I am going to attempt to use my lint roller and try to get most of the fur off)

Are most brand socks machine washable?

Do they shrink or lose color? Just a little curiosity ^^

Thanks for looking!
