I'd like to say I have had good experiences with these critters but I have not. My brother had one when we were kids, and after letting it run around his bedroom for most of its life, I was in the room when the rat finally decided to die.
That was not very pleasant to watch, and quite spontaneous.
Then there were the rats that lived in my roof when I used to live in Malawi about 10 years ago. Scratching all night long. The rat poison out there is very strong, some might say illegal. But it worked. The rats went crazy one night, then nothing, then the smell. God, that was horrible fishing those things out of the attic.
And because the poison was so strong I had to burn them to avoid the dog digging them up if I buried them. That was both the first and the last time I used petrol to start a fire. It really does go up like on the movies! Until that point I had kept a 5 gallon plastic can of the stuff in the house. After seeing just a fraction of that petrol ignite, I'll never keep more than a quarter of a gallon of fuel indoors again. I do not even like doing that but you bloody Americans are obsessed with gasoline mowers. Why can't you just use electric ones like the rest of the world?
Oh, I forgot....110 stupid volts don't get you very far.
