No shame in that

. I used them briefly but no plans to ever keep them again. I like the fennec Fox more.
I made a nice little arctic fox house habitat, for use in temperate or warmer zoos. It was very pretty, with an arctic tundra roof, but alas the little critters kept escaping through the glass and making my guests flee in terror. I did it again, from scratch, in a different zoo, and I had the same problem. Gridded paths partially surrounding an indoor arctic fox habitat simply doesn't work for some reason. I've had a similar issue with the caimen when I tried to do an exhibit like this for them (but in a nice, heated tropical reptile house). I don't really like tundra and taiga zoos (too cold for most critters), so I haven't done much with them since.
There are a few other critters like this--constantly escaping, or even just registering as escaped when in the middle of their habitat. I have a problem with lemurs too, but I love them so much I put up with the occasional alarm bells that ring when they are still in their habitat.
Someone mentioned preferring pygmy hippos to hippos also. The pygmy hippos are so darned cute, and they take way less space. Trivia, they are less aquatic than their larger cousins, and they are rather nocturnal. Maybe they should be in the twilight zoo.
The in-game requirements for hippo space seem much greater proportionally than what one sees in real zoos, even really good ones.
They have a
nice hippo habitat at the San Diego zoo w an underwater viewing window, but it doesn't seem to be as large as they have to be for the game. I did try a hippo habitat once. Spent a lot of time building a deck out over the pool with an enclosed area with stairs down to an underwater viewing area. I spent a lot of time making the hippo underwater area look realistic with water weeds and rocks and stuff. I finally filled it with water and plopped some hippos in, and I got not enough traversable water area. Evidently, since they "walk" on the bottom of their water habitat and don't swim they won't walk over rocks or weeds. At all.
I had to take most of it out and ended up with a bunch of bare mud that looked cruddy.
Maybe that should be its own thread: habitats you spent a bunch of time on and were proud of, but they didn't end up working at all for the animals or guests.
