The TICA show coming up New Years Eve... I'm a little confused with how the cages work. I'm bringing 3 cats and they allow 2 cats in a full size cage and right now I've signed up for 1 double cage and 1 half cage. Which I assume would be enough space. What on earth is a half cage? At the CFA show I went to I didn't see any half cages so it must be different. Is a half cage enough for one cat?
