Large enough...

...box for the kittens, with room for growing. The monitor that came in it is definitely big enough for me. The old one served me well for 13 years and it was bought used, so a very good service life for IT equipment. It still works, although sometimes there are moments, when the resolution setting goes crazy, and I must admit I have wanted larger for some time.

I couldn't leave the box in the house, too big to keep in any corner. The kittens definitely would have liked it.
