Pet Doors & Lock access for doors from pets

I can only assume this is already a consideration for the game.
but i would love to see different sized pet doors for cats and dogs.
with only cats being able to fit threw small ones and dogs threw bigger ones, similar to how the Sims Pets did it.

additionally, another thing that Sims did well, was allowing us to lock access to certain doors for animals, i would love that feature in this game so i can make dog kennels and catios to keep my pets in
