Hybrids are produced when you cross-breed 2 different spieces.
My favorite hybrids are:
(1) I bred my cat with a rabbit, and got a cabbit.
(2) I crossed a mink with a weasel, and got some measels (wink, wink).
(3) I bred my cat with a ferret, but she just gave birth to a fat carret.
(4) But gerbsters are REAL (or are they?).
