Anytime I end up with something new, my husband throws a fit. A few days later, I'll catch him sneaking leftovers to them or just sitting and watching them.
Our current crew:
5 Buttons
100+ coturnix eggs on the way
2 parakeets
13 fish tanks that are running (several others that are dry)
2 dogs
1 cat
3 ball pythons
1 corn snake
9 rats
We also occasionally have mice (domestic of course), plus we have a mealworm farm, confused flour beetles, several flightless fruitfly cultures, grindal worms, microworms, walterworms, bananaworms and vinegar eels. These all take up minimal room though, and aren't generally noticed.
