you mean the are too wide for the doorway ? LOL I have that problem too. they wont turn sideways. might consider making it a little wider if possible but I bet they can. they maybe unsure of their surroundings still. throw some yummys on the ground and walk away. check on them in half hr.
Not wide, but tall. The ramp comes up through the floor of the loft. The angle of the ramp makes the opening small.
