### Instruction:
Jamie owns 4 Persian cats and 2 Maine Coons. Gordon owns half as many Persians and one more Maine Coon than Jamie. Hawkeye owns one less Maine Coon than Gordon and no Persian cats. If they bring all of their cats together to play, how many cats are there in total?

### Response:
Gordon has 4/2 = <<4/2=2>>2 Persians.
Gordon has 2+1 = <<2+1=3>>3 Maine Coons.
Hawkeye has 3-1 = <<3-1=2>>2 Maine Coons.
There are 4+2+2+3+2+0 = <<4+2+2+3+2+0=13>>13 cats in total.
