This varies a bit with the cat. The absolute minimum gap a cat requires is slightly greater than the height of its skull (cat's heads are wider than they are high). There are videos of kittens forcing their way under a door which has about a one-inch gap; for most cats, it seems two and a half to three inches is the minimum.
Maybe about 40-50... But if it's a big cat it may be 80-90 in..... Idk but i do know because i wrote three essays about cats.
if a cat's whiskers fit through, the rest of it will fit, too.
It all depends on the size of the cat and the size of the opening. The question gives no indication of the measurement units. Centimetres or inches is far too small a gap for even a tiny kitten to squeeze though. If it is metres or feet, then even the largest domestic cats will be able to fit through.
3.6 feet (not fit!) equals 43.2 inches
Yes, the peg will have a diameter of 0.955 inches which would allow it to fit in the hole.

Put a cage around it , then have a small hole that only the cat could fit through.
As long as you can get it through the door.
Nope - it's at least three inches too big on its smallest dimension !
