We have had Leroy over a year now. He still acts like a kitten even though he is bigger than Hagrid. On Sept 20th Hagrid will turn nine. They still chase and play fight with each other, but it is a more even match these days. Hagrid really cannot go anywhere without Leroy following. Here are some great pictures of them.
Leroy has to do everything Hagrid does.
Leroy likes to sleep on, sit on, and always be in Hagrid's way.
