I am the Wife in this situation-- but my husband doesn't care either way. I have 2 kids-- both under 3 (one will be 3 this year)
I have large snakes, small snakes, and everything in between.
We have big girls up to about 15 foot-- and little ones-- our smallest is a rosy boa-- actually is my son's pet-- the snake is ontop his dresser-- teh dresser is attached to the wall and the aquarium is attached to the dresser. Every other nite or so we change the water, I reach in and pull it out, he dumps it in the sink and refills it- i put it back in.
Anyway- With our big snakes-- we have a 2 1/2 car garage, we bought super insulated doors, insulated the walls and celing, installed central heat and air-- all our big snakes are out there. All of them have locked cages as well-- the keys are usually in the locks-- in case of fire/similar crisis- we dont have to hunt for keys. The door to the garage is also locked-- the lock is at my head level- and also has the key in the lock.
The biggest snakes we have in the house are the 5 foot retic and a 5 foot emerald. the emerald is in our room, also with locked cage- the retic is in the living room.- also locked.
We are buying some new cages with next years tax return- one will be a new retic cage and will be going to the garage.
I also do a LOAD of events--- educational, b-days, rescue events, etc--- all of which involve children.
I will post a pic that has brought up a lot of controversy before-- the pic was taken by the photographer, of the photographers kid- You can see in the back ground that the other kids are at the end of the snake, and sitting down. The photo-op was a far and few between occurance for us.
