Your Generic Male Protagonist’s house is being fumigated. He decides this means he has to take the cat to work with him.
His work at the highly restricted chemical lab which doesn’t allow pets.
He must’ve known that his house was going to be fumigated for an extended period, yet there are no nearby kennels, and he has no real friends. Except, of course, for his friend and co-worker, who has two cats of her own.
Why doesn’t he ask her? He’s shy.
So he puts the cat in the utility closet, and she’s accidentally released when GMP’s boss comes looking for him with a pink slip. That’s reasonable. What is somewhat let reasonable is that the cat is able to see multiple people, none of which notice the orange cat hanging around, and then the cat manages to knock over several dangerous chemicals and start a major fire.
GMP rushes to see to it, and not only does the lab not have any sort of fire procedure or tools or exit, the nearest fire extinguisher outside the room is in a sealed glass box that has no way to open it. Our zero has to punch the glass case open. It’s not even safety glass, and he cuts himself. And what does he need it for? To crack the glass door to the lab, of course, because if there’s some kind of button for exiting in the event of an emergency, it’s not working. At all.
Right, that’s my suspension of disbelief utterly wrecked, and at about three pages in. Good job.
