Phase 1 - Get supply
You'll see, Goro.
Phase 2 - Build interface
Phase 3 - Install
And here it is - tunnel to Goro & Niko's enclosure
Phase 4 - Let them use it
You push the door to go outside, Goro.
Adventurous Goro started going out
through the kitty door & tunnel soon.
But still needs assistance to come back inside.
As expected, cautious Niko is hesitant to use the tunnel.
Phase 5 - Convince Niko that it's not scary
Niko stuck out his head through the door, which
is the most progress he has made so far.
It's okay - we use regular door until he feels comfortable.
Tunnel project will be complete
once both Goro & Niko enjoy using it.
After that...we just enjoy ourselves :-)
