Cats nowadays

I'm not sure if I should be happy or sad that my cats have no interest in that game whatsoever

Look that their little paws. :)

Speaking of cats Im fostering a kitten for two weeks.My grammy had wild kittens in backyard,mom didn't want them.She took them in,my neighbor wants one but she's away for two weeks.so I GET to babysit it.......she's really cute and small still but she's also litter trained :D.So we have a litterbox n stuff,it's awesome.Only thing is that it was really sad bc she brothers and sisters and we gave her the proper good bye,but she was crying and meowing the whole way to our house.... ;_;.Also we have two other grown up cats and they aren't very happy with her.Wish me good luck

They look a bit chunky, maybe they should be playing with string...

What game is this, please?
