Soon after our dear Midnight passed away, the Foodie daughter asked - once again - if she could have an aquarium. Now, given the fact that our Middy was an industrious and single-minded cat, an aquarium filled with little swimming bits of goodness was a very bad idea. The dear kitty would never have rested until he had gotten his teeth on those small tidbits.
However, we were now a Middy-less home and I relented. Of course, I added the caveat that the daughter had to pay for the aquarium, fish, etc. and take care of the thing. (Silly mom! What was I thinking?!)
