It is not a rare sight in household cats, especially if they have long fur. So, naturally, it is much easier for a cat with long hair to get poop stuck in its skin than for a short-haired cat.
So what's the problem? The number one culprit is diet. Think about it: what we eat as humans affects the consistency of our poop, and it's the same with cats.
Other possible issues besides dry food could be that there are allergies. For example, food allergies can modify the consistency of the cat's poop and make it sticky.
Normal cat poop is quite dry but not dry enough to be edgy and get stuck in the cat's fur. This is why getting poop in their fur is not typical for cats.
On the other hand, the looser the stool is, the sticker it is. Semi-solid stools or mushy poop are easy to stick to the fur and challenging to get out .
Large pieces of poop caught onto the cat's fur - These are easy to see and smell. As you can see in the first picture, cats can get quite large pieces of poop stuck in their fur.
