I think he is a very clean little guy- first he kills his prey and then he puts it in the food bowl where it belongs

No- I think Malachi is just a kitten and he is a naughty and active kitten. I suppose this is what causes havoc around him now. I remember Filou and Tigris galloping through everywhere- you really thought they were mental. Filou still can be like this- he's a full blood Aby after all. In Tigris his share in Siberian character became more important with age so he is calm now.

I just love Malachi- IMO he can't do wrong
