* Cat size: A small kitten can squeeze through much smaller spaces than a large adult cat.
* Cat breed: Some breeds are naturally more slender than others.
* Flexibility: Cats are very flexible, and can contort their bodies in surprising ways.
* Motivation: A cat motivated by a tempting treat or a sense of curiosity may be more likely to try squeezing through a tight space.
Generally, a cat's head is the limiting factor. A cat can often squeeze through an opening that's about the size of their head. That said, they can get their whole body through a surprisingly small space!
Here's a rough guideline:
* Small kittens: May be able to fit through openings as small as 4-5 inches.
* Average adult cats: Can fit through spaces around 6-8 inches wide.
* Large cats: May need openings of 10 inches or more.
Important Note: It's not always safe for cats to squeeze through small spaces. They could get stuck or injured. It's best to keep your cat away from any areas with openings that could pose a risk.
