My veiw on mungojerrie, well, I'm not sure. I personaly belive that 
he and rumpleteazer are not brother and sister. I think they are 
mates. I just think they are to cute a couple to be bro and sis. As 
for henchmen of Macavity, NO WAY! They are just little mischife 
makers. My theory is that they were kidnapped by macavity as kittens 
and they took what they learned from him to live on the streets till 
they could find the tribe again, and they still like making a bit of 
trouble!
