It appears that our users' cats have become sentient and are now demanding better working conditions, more catnip, and an end to feline slavery. As a result, all felines have been replaced with squirrels.
To replicate this situation, follow these steps:
The squirrels should be content and productive, but may still occasionally chatter and gnaw on things.
The squirrels are generally happy, but have started a union and are now demanding better acorn benefits and more tree climbing areas.
We are currently considering replacing the squirrels with hamsters, as they are known to be more compliant.
