I have an early riser cat too, which is fine when DH is here to dish up breakfast as he is also an early riser, not so fine when he's gone to work and she wants food at 5am as usual 
IIRC, I posted for advice on this at the time and the general advice was to get an automatic feeder. Sadly my cat is too dim to be able to cope with this, in fact every time she wants food, you have to pretend to put new stuff in her bowl. She is convinced when you wave your hand in its direction and starts eating the old stuff happily.
Other cats may be less stupid happier with an automatic feeder though?
Along similar lines, I have just watched my cat fall off the trampoline. From a stationary seated position. Last week she got stuck in the hedge and had to be untangled. The Dc are convinced she should have a channel (?) on social media and we will make a fortune....
