This 'house' was empty for many years before Tigger made it his own. Now he sleeps in it every day. He's done so for almost 2 years. It's strange how cats will ignore their toys or sleeping beds for a long, long time and then start to use it for no reason. When Tigger was a kitten, he used to carry this furry, white toy mouse all over the house. But when he grew out of kittenhood, he abandoned his toy and we soon lost sight of it. Earlier this year, it made its reappearance as Missy's toy. I have no idea where she found it (shows you how well we clean our place), but she'd play with it by herself and carry it from one part of the flat to another. She'd also carry it onto our bed and meow loudly, wanting to be praised for being such a good mouser, even if it is a toy mouse! Shortly after Missy started playing with it, Tigger did too. But in the last week or so, 'mouse-mouse' has fallen out of favour again and now just lies on my bedroom floor.
