Partnering a cat with love 'off'

[Liriel Garnet]

Someone said in chat today they'd accidentally partnered a cat with a cat too old to breed, and asked how to split them up. I didn't think this sounded right and tested to be sure with a cat i'd just pulled out of my breeding lineup into inventory and a 132 day old pet -- sure enough, it let me partner them.

? Princess Nyn

? 132 days ?? Off ? 91%

?? 95% ?? 11%

Partner: Still Waters
(10 days remaining)

This really needs to be hard-coded that a cat with breeding off won't accept a partner.
