Since Wildcard patched the cat throwing into the water, there is a workaround. So if the cat is red (not tamable), you can go to another map with your character and then log out. Then log in to the map with the cat, I then had a green symbol, tamed it and released it (also works in a public box in the cryo), then parked the character on another server and switched to this map with the current character and claimed the cat. just workaround.
