When Fister first came up, he just could not figure out the doors, but now he can certainly open them - and not only doors!! If he thinks we're out for too long (more than 4 hours) we can be pretty sure that he has opened every single cupboard door in the flat, he especially likes to lay on our shoes in one cupbopard.

The funny thing is though, that he can only open doors by pulling them - he hasn't figured out yet that they can also be pushed open!
