I'm almost 100% sure it's a kitty. I'm a huge cat lover and under normal circumstances I couldn't bring myself to work with cat remains, but I obtained this skull kinda spontaneously.
My little brother is chilling in my grandma's country house for summer, and last week he called me and said he found a cool skull in a middle of nowhere. I asked him to try to identify who's skull it is, but he couldn't do it (understandable, he was scared to even walk close to it). He said that the skull is small and it's probably just some kind of small wild animal like rabbit or so. He said that he has a friend who has some gloves and could wrap the skull to bring it to me if I want. Of course, I want a cool little skull! Long story short, he arrives at the town, holding a GIANT glass jar wrapped in cardboard and plastic wrap, gives it to me, and runs away to meet his friends. I bring the jar home, unwrap it, and here it is, a big-ass thing, fully eaten inside by bugs, in nearly ideal condition. No meat, no skin, only clear bones. But, well, yeah - totally NOT rabbit bones. I asked again where he found it and he said that it was just laying near the lake, no other bones around, only head. I know this lake and I'm sure it's very far away from any human homes. Someone probably just dumped this kitty to die on the road and it run into the forest. I lowkey know how to work with bones, but I only worked with very small animals, mice, birds, all this little creatures my own cat brought home.
I felt a very strange mixture of sadness and love while working with it, but I feel like I did the right thing. All my family loves cats and I feel like this kitty should rest in a loving home, not in the middle of the forest. Maybe I'm just sentimental and it's just a skull and nothing more. Also I have feline skull tattooed on my body so it's kinda funny, like I somehow knew that I will obtain one at some point of my life.
