Well, I dont know the actual breed of the cats, but i well say what I know.

Garfield is a old light orange long haired cat
Gizmo was a {baug}(gray and white mix) long haired old cat. he had to be put down.
Bizous(aka Bizness, bizzy) is a young dark orange haired cat
Tommo(or Tomo) is a young {baug} (gray and white mix) haired cat.

The two young cats are short haired replica's of the old cats. Its kinda weird. orange cats are fat, gray/white ones are thin.
