Answering my own question...

I think the answer to my question the other day about how these super mega-moms do it, is this - they have no animals. So now, I am just biding my time until our menagerie's time is through.

The fish, no complaints, Brynna has trouble pouring him into a cup when she cleans the bowl, so she asks for help. The help? Oh, that would be me.

The three turtles, pretty painless, except when they escape and need to be found, signs need to be posted around the neighborhood, guess who does that. Oh, that would be me.
Three times a year, roughly, their pond needs to be emptied and refilled, guess who that job might fall upon. Oh, that would be me.

The dogs, where do I start, Calli, the teacup poodle bites a child every other day (not that they don't deserve it), but who has to take care of rescuing Kujo from Dennis the Menace and tend to injuries? Oh, that would be me. Puppa, the stray that was never claimed, is a great dog. The kids could probably remove some major organs and the dog would just try to nudge them away, however, she sheds and who has to sweep and vacuum everyday(Okay, at least every other day)? Oh, that would be me. The dog also poops. Not little Calli poop, but big dog poop. The kids for the most part clean it up, but I have to constantly remind in a loud voice so they remember. On the days they don't though, who's cleaning dog poop out of tiny toes? Oh, that would be me. To top it off the dog's in heat and keeps sneaking in the house. Right now I'm nursing and "my friend" isn't visiting for the next year, I don't want to be entertaining hers - but who is running around with a wet paper towel swiping up drips? Oh, that would be me.

As for the two rats, giving them to Brynna was the best gift Brian and I have ever given, but their huge cage needs to be cleaned often so that my kids don't go to school and become known as the "rat pee kids". Guess who takes care of the rat cage. Oh, that would be me. Also, if their cage does not remained centered on the wall then they chew whatever comes near, i.e. my couch, the speakers, toys, etc. All day long, I constantly am reminding Keely, in a loud voice, that she needs to leave them alone. She knows how to open their cage and tries to take them out against their will. I'm sure removing her, removing them takes up at least 30 minutes a day.

The kids are responsible for all of the animals and they assure me with each new addition that I won't have to worry about anything, but they're kids and their priorities are not always aligned with mine so, who has to pick up the slack? Oh, that would be me. I know what your thinking, get rid of the animals stop your griping.....but then they cry. Huge tears that roll down their cheeks accompanied by sobbing promises and whose heart breaks a little and thinks, "It's not that bad"? Oh, that would be me.
