Letting them out is not a problem. Putting them back in this when the fun begins.....
It is kinda like the Hokey Pokey, but with kittens.......
You put 5 kittens in and get 3 kittens out....
You put 3 kittens get 2 kittens out.
You do the Kitten Pokey and turn yourself around, thats what its all about!
This goes on for twenty or so minutes. The kittens just want to run and play at this age. Trying to hold them is next to impossible. As you try to catch them you get frustrated, but they are just too adorable!
All you can do is laugh and then cry a bit.
