Bob and Marley are too smart.
Bob is not allowed outside because we live by a major road and it is simply too dangerous. Marley is allowed to hang out in the patio. Marley has taken it upon herself to open the sliding screen door for Bob and invite Bob to hang out with her.
I do not find it funny when Bob tosses things off my desk for Marley to chew. My stack of papers on the floor is fine; however, any paper that falls off my desk must be extra tasty. Marley especially likes falling pencils.
The good news is they will probably not conspire against me as long as I control the cookies.
