Life Lessons in a Pet Store

Okay...so I spend a great deal of time and money at Petsmart. I should own stock in Royal Canin. Each four-legged roommate requires a different formula perfect for their delicate digestive systems.
So I was on one of my many trips to Petsmart earlier this week to stock up on supplies. When I got to the appropriate food isle, I realized there were only small bags of "Pug Formula" instead of the larger bag we require in my household. With arms loaded up with multiple, small bags of puppy chow I headed back to the front of the store to retrieve a shopping cart. I'm good but I'm pretty sure weilding the 50 pound bag of "Senior Formula" with the other bags would have been pretty much impossible and totally laugh-able.

As I'm walking towards the doors, the fishtanks caught my eye...so pretty! I watched a beautiful, small stingray swim gracefully in its tank. Clutching my bags of food I wondered if I should consider starting a saltwater tank but I've heard they're horribly difficult to maintain and one high maintenance item in the house (moi) is enough.
While pondering the "to fishtank or not to fishtank" question, the stingray gracefully glided up to the side of tank exposing it's pale underside, slapped its body against the side of the tank (trapping an innocent by-stander fish) and began to slurp its prey through an opening in its abdomen. It was disturbing. I stood there with my mouth open, clutching my precious Pug Formula and watching this sloppy eater devour a precious, little fish.
I was not the only one watching. I looked down and saw two little girls who could not have been older than four or five, holding hands watching the scene much like I was; with their mouths open and in complete shock.
The older of the two turned to me and asked "That mommy fish just put that baby fish in its pouch, right?"
How am I supposed to answer this? My sister is a vet so she's pretty open with my three year old niece about life and death - maybe I should be? But what if it freaks them out and they start to cry? I don't want an angry parent chasing me down! Besides, I wouldn't be as nimble loaded down with dog food.
My Answer: "Well if by "baby" you actually mean "prey" and by "pouch" you actually mean "mouth or gullet," then YES! That's exactly what happened!"
I did a quick sweep of the area for their parents and then I darted for the carts to complete my dog food mission. This also settled my delima on whether "to fishtank or not to fishtank." I'll choose "not" so that I don't have to have these daily life lessons.
