If the cat came back, the very next day … why not sign it up to be your companion? Pets of Skyrim lets you do just that, selecting from 16 cats, 11 dogs, three rabbits and one wolf (poor lonesome fella). You can fiddle with colors (10 for cats, four for dogs) as well as sizes, say, if you want to make like Jon Snow and roll your own Ghost.
