Copycat, I request permission to plant a Cyanfruit tree on the grounds.... or two.... or three.... 
If you can find a real Cyanfruit-tree anywhere, you have my permission to plant a couple in the Asylum garden.

Now if you can figure out a way to turn the guard cats into zombie cats, you'll be all set.
If you were to try any type of genetic tampering with the guard cat's DNA (not that you would be able to get a hold of it anyway) you would soon make acquaintance with their claws.

Maybe? It depends on how intelligent the guardcats are. 
Very.

You could always try it and see.... not that I would recommend doing that to the guardcats, being an official staff member of the Asylum and everything.... *Shifty Eyes*
Indeed, you better to recommend it or you're fired. Even this suggestion has put you on probation.

we could plan a new escape 
You could, not that it has any chance of succeeding, mind you.
