He said "Nope"

Rusty isn't one to want to go outside as much as Keiichi does, but Keiichi tried to coax him outside. But Rusty just sat back and watched as Keiichi went outside to get some fresh air instead.

This is probably his favorite spot outside. Just chilling on the patio and checking out the new sites, sounds and smells.

Some geese flying south overhead spooked him and caught his attention. He loves all of the new experiences he gets while he is chilling in the backyard.

He wasn't a fan of the cold wet grass this morning though and didn't want to spend anymore time in the grass than he needed to.

I think he was done with the outside at this point and ready to go back inside and chill by the fire place.
