What are good 3D animal games that are easy to download but really fun

Some good games that I know, and have personal experience playing with are:
1. Feral Heart (Really fun, 3D, customizable characters and roleplay)
2. WolfQuest (It's fun, but can get boring. Beautiful graphics, cool maps, limited online chat and roleplay ability.)
3. Sanctum Of Eventide (Similar to the Feral Heart game, but you can hunt, get items, customize your character, and explore endless amounts of maps.)
Hope this helps! :) All are extremely easy to download!
