Kitty and tweety at the same time.
Said: I will file the information away for possible future use if and when my home becomes cat-less.
(Is there a good joke there, somewhere?)
Rich: I had a cage of parakeets recently while my cat was still alive. I suspended it from a hook in the basement ceiling, (that part of the basment is finished), in such a way that the cat could not jump up directly or from any adjacent surfaces.
The cat would sit at the top of the basement steps [a direct line of sight] steps and watch her *LIVE TV*. I was also able to keep the mess off the main floor, while monitoring them constantly to make sure the cat didn't get too interested.
Of course, I was a good mommy by not reprimanding the cat for her natural inquisitivness and instinct in them, but rather diverted her attention away when she got too excited. I was especially careful when the cage was on the floor for cleaning.
