No question for a cat.  Fences are at most obstacles to be traversed.

A bit different with dogs.

And – believe it or not – we humans were the ones behind the fence.  And the shepherd at the back of this herd kept shouting: “Close the gate, close the gate! They’ll overrun you!”

“The wide world is all about you: you can fence yourselves in, but you cannot forever fence it out.”

– J. R. R. Tolkien
