> While dogs slowed down and hesitated before they attempted to use an uncomfortably small opening, in the case of cats, we did not detect this change in their behavior before their attempt to go through even the narrowest openings. However, remarkably, cats showed hesitation both before they attempted to penetrate the shortest openings, and while they moved through it.
I just skimmed, but I didn’t see any mention whiskers. It’s seems to me that cats can make highly precise measurements of width just by sticking their heads in a space, but height judgments requires additional consideration.
> Cats are also aided by their large and sensitive vibrissae, which are positioned on such locations of their head that the cat can detect nearby obstacles in closer encounters. Vibrissal sensation can compensate for the somewhat weaker vision in cats from closer distances or in poorly illuminated environments. Therefore, it is possible that cats approached the narrow openings in our experiment without differential hesitation, and they could use their vibrissae to assess the suitability of the apertures before penetrating them.
Oh thank you! I’m just a lowly cat owner and did not know what vibrissae are.
If you have ever put a cone on a cat (which lasts about five minutes), you see they get crazy. They hug the walls.
Their whiskers are a major factor in their perception.
I think they can also dislocate their spine.
My cat likes to sit in what we call his "Buddha" position, with his back bent about 90 degrees, and his paws in front. This seems to be a common position. He'll sit like that for an hour.
I think the cones must also screw up their aural spatial sensation (changing their perception of sound from fairly omni-directional, to seeming like all the sounds are coming from in front of the cone).
My cats are weird and loved their cones after they got neutered. One would stick his head back in the cone after I took it off.
I think all cats are weird in their own way. Our cat often sunbathed in the middle of parking space across the road. We occasionally had to go out to fetch him because he would refuse to move when someone started to drive into the space.
I've seen a few people use a soft inflatable or plush collar that's more flat, and doesn't go up around the face, instead of an actual cone. That way the cat's the whiskers aren't disturbed while still preventing the cat from worsening wounds by licking. At least some cats seem to be a lot more tolerant of that style.

From skimming the HN comments:
> Wiskers are mentioned, but using the scientific name - vibrissae
