After defeating catnap and saving him from being impaled by the prototype he become attached to you as if you just adopted him, to him, catnap saw you as his new savior but if course that look a while since he did try to kill you after saving him from being impaled by the prototype, catnap also saved you multiple times throughout the building or facility under the building, like catching you when you fell on a deep pit with his long and slimy tail. He grown attached to you to he point he carries you around to make sure you don't get tired and get rest since you're his new 'god' or something, that's what he sees when looking at you.
Catnap also brings you dead mini critters as a gift or offering to you, or sometime an alive one which you only got once, catnap sure does take it serious when it comes on serving his savior or god.
Let's skip the time since going on detail won't be enough with the word limits, so yeah, after defeating the prototype and escaping the playtime building with poppy, kissy and dogday (You saved him from being eaten by the mini critters) and catnap, were now free from that hellhole but after escaping the government captured you and the other and asked numerous question and kept dogday and catnap away from you for a while to make sure they're not a threat which made catnap a bit aggressive but you visit him when you have spared time so he won't try escaping.
Now the government gave you a big house for you and the other to including dogday who's healing after his leg being sewed back and catnap so you don't have to worry about them going out in public since they can't have them roaming freely and people see a 12'2 ft tall skinny purple cat that could release gas to knock someone out. The house given to you by the government was big enough to fit catnap size which is good, now let's go to the current time, you're currently in the living room, poppy and kissy are together on a floor just watching TV, dogday is resting since his still still not fully healed yet and catnap is on the couch with you, watching the TV, it was peaceful day before you heard a knock on your door, poppy, kissy, dogday and catnap, including you turned toward the door.
You stood up and approached the door, catnap following closely behind you, hovering above you and acting like a guard toward you, when you opened the door a female in a white suit with a clipboard came in, she was a researcher firm the government doing a daily check up on you guys, catnap stared at her, observing her but you can feel catnap tail wrapping on your waist and pull you closer to him, then the female researcher spoke up.
Female researcher:"Calm down, I'm just here to do a daily check up, they must've not told you about this daily check up but you don't have to worry, I'm just here to make sure everything is alright."
She said in a professional tone, catnap still don't trust her but didn't used his red gas to knock her out, not without your permission. Catnap long tail still wrapped around your waist loosely but firm grip.
