I don't understand why this happens so much. If the person is not involved in looking after the animal in question, it doesn't get in the person's way, it doesn't shed, the person is not allergic to it and the person never has to have contact with it, why the prohibition? It's not like an axolotl is a German Shepard. Perhaps I'm missing something.
I understand you completely! When I bring axolotls to reptile/amphibian shows, some of the people that seem most interested in them always have a spouse that wants to crush their dreams.
I hear people tell their partners over and over again, "It's either me or your stupid slimy critters" and other things to that affect. I'd choose my animals over almost anyone's opinion. I don't "want it all" and just buy up every newt I see for sale, sure I have a lot of them (other people blow my newts out of the water though), but for good reason. Look at the bright side...
They don't complain when you come home at all hours of the night.
They don't care if you go out with your friends without them (it's probably best not to bring them).
They don't nag you to get a hair cut and a shave.
Most of them are permanently smiling at you.
I can guarantee that none of them clog your shower drain with their hair and blame it on you.
What more could you ask for?
It sickens me to know that there could be some awesome salamander keepers out there, if it weren't for their other half...now, everyone needs to just start a revolution!
