Very heartwarming, with simple and mellow gameplay that fits the mood.
I like the use of the thought bubbles for the cats' needs. I don't know if it was intentional or my browser started to lag, but the the game went into slow motion when the last cat went - I thought it was a nice touch.
The drop areas for the nipple and bed was a little inconsistent at times, which was noticeable when having to attend to multiple cats. Perhaps the drop zone could have been larger.
It was definitely an enjoyable, feel-good game.
