Testers wanted: Vivarium (zip & rar)

Thanks to twojeffs I was able to fix the menu so the sims can look at this!
It's a vivarium with a little kingsnake in it.
I have tested it in the game for about a week (sim time) and had no problem with it, let me know if you do.
Only thing I noticed it that they seems to stop looking at it very quickly, I don't know why and I don't know how to change that.

I don't have the EP yet (I hope I will get it today) but it should be EP ready.

Edit: added zip file.
