Well, my original plan was to give equal time to pets of the canine persuasion with another suitable fractured idiom, to insure that our feline companions wouldn't feel overly put upon, but I'm afraid that I simply had too many dogs in the fire at the time. Then again, if I'd done that, I might have been accused of burning my bridges at both ends. Fractured idioms are fun, but it's not rocket surgery, after all, so there's no need to reinvent the cat's pajamas.
Yes indeed, simplicity is beauty, as they say. But I also find it very enjoyable to discover that, just when you think you've got all the ground-rules figured out, there's more than one way to nail jelly to a cat.
It's much easier to spread the jelly on. Fewer stitches too.
