IIRC, rabbit droppings are round like you show, and deer are like flattened balls.

So, I say rabbit. Fur looks like rabbit also.

nah that's not rabbit. 100% deer.

hair: hard to explain how its deer, but the part of the animal that is visible is the brown with the white tip, the rest is just insulation. If you have ever experienced a deer kill you would see clusters like this one all over the place.

scat:The great thing about poop is that it never looks the same as the next batch. I'm sure you have noticed how your morning poop highly reflects what you ate for dinner the previous night. Poop will change consistency and appearance depending on your diet.The one thing about this cluster of animal waste that resembles rabbit is in fact its diet. The deer seems to be feeding primarily on grass and woody vegetation which is what you would see very often in rabbit scat. Scat like this is something you would often associate with winter because of the lack of green vegetation. In spring and summer deer scat will often have indentations in their pellets which is a characteristic of their digestive system and is what chuckr30 is referring to. The real identifier is the oval shape () of the scat as opposed to very spherical O shape of rabbit scat.
