Here are four 3t2 objects from The Sims 3: Pets EP. They are all fully functional and feature all of the original recolours! You obviously need the Pets expansion for these to work. ^^ The cats use the castle as a gigantic climbing post and will sometimes emerge out of the tunnels or clip through, depending on its routing.
And while you're at it - click to give free kibble to shelter animals in need.
Do you like what I do? Then I'd love if you donated. Any amount helps!
