Cat on MP Hungry

[Tad Carlucci]

Cats cannot eat when in your inventory (which includes on the Marketplace). They also continue to get older.

The best way to sell live cats is in-world.

I think most people restrict Marketplace sales to boxes, where none of these issues occur and the box is completely unaffected by the passage of time (except some may be so old they'll need a laying-on-of-hands from a CSR to update them).
