Why you no?

Please help me out!

Here's the deal:
The last few days my dinosaur is looking really bad, and he doesn't eat as much. I'm afraid he might die soon.
Apart from the fact that I'll miss him a lot, I'm concerned about what would happen if he would die while I'm indoors.
Obviously I'll lose the ability to open doors, and I won't regain this ability until I've purchased a new dinosaur, which will be really hard
considering the fact that to leave the house (and to enter a store) I need to open doors.
I don't want to be locked up for the rest of my life.
How do you combat this problem?
