"Disable" Pet Option
No.
If you get into combat he goes out again.
The easiest way to implement this would to have a blank option on the pet selection screen.
They remind me of the real pets we all have at. You know get weekend alone with your wife hope into bed things start getting hot and suddenly who pops out (the pet) Then hops up into bed because he now thinks it must be bed. Starts kitten blocking by laying in the middle right between and wanting to join in with the kissing . F&N hate pets they seem to pop up at the worst times.
