At a quarter past midnight when I was just about to go to bed, I noticed Nysse in my bedroom, which is unusual for him, and behaving oddly on top of that.

A closer look showed the reason: he was playing with a mouse that he had brought inside.

The mouse was physically unharmed, but probably panicking, of course. Nysse wanted to play and sort of softly batted the mouse about, not particularly aggressively at all. The mouse tried to flee a few times, but mostly stayed as still as possible. At one point it ran into the folds of my morning robe and Nysse, who had been looking the other way, basically lost him.

I ran to the kitchen and grabbed a plastic jar with a lid, hoping desperately to get back before Nysse lets the mouse flee again and it goes into hiding under my bed or something like that. Ran back again and saw the mouse in relative safety in the corner of the room, in a freeze response. It didn’t even react when I put the jar over it – like I’d do with a wasp or a spider – and slid the lid underneath. Easier than catching a wasp, actually.

Snapped a quick photo and released it into the garden. Then threw Nysse out as well a couple of minutes later, because he was still in a hunting mood and was running around and looking for things to attack. By that time the mouse seemed to have disappeared.
