"What if they have less than 4?  Or none?"

He chuckles.

"No arachnids or bugs, they are considered creepy crawly to some."

He heads into the house, carrying the plates and utensils to the kitchen, setting them in the sink then goes towards the opposite end of the house into the bedroom on the right at the other end of the house.  Inside are a few snakes and some bearded dragons, plus 2 iguana.

"Here are my pets."

Stepping inside the male iguana he has starts bobbing his head at him.

"Oh I know, it has been a while."
