Well, I'm going to go ahead and divide it like the others-

reasonable/already planned:
a wiener dog (which we should get sometime this year)
a whole pit of BPs (some of the high-end morphs go on the other list!)
a retic
GTP
another stinking cat (had a few, don't have any now- wife wants one again)

unreasonable:
English Mastiff (we're in a duplex)
a couple of horses
