This is my OC, Shadow. I created her a while ago.. prolly a year or two ago when I created my human OC, Jason.
She's genetically mutated, so no, she's not a panther or anything. She was originally a small, domesticated feline. Her fur color was solid black and she had blue eyes. After she grew into her mutation, she formed three zig-zag stripes on her back, silver tipped tail, silver toes, silver inside her ears, a silver muzzle, and silver patches around both her eyes. Her eyes remained blue, and he nose is a dark pinkish red as well as her paw pads.
I don't want to explain too much about Shadow relating to the story, because that'll give stuff away~ She's Jason's cat, though, and is a good companion just as a dog would be. She's loyal and intelligent and can comprehend human emotion and general human language. She's not too big that she can't maneuver through small spaces uneasily, and she's also not too small that she can get beaten down quickly. She has a higher percentage of muscle mass in ratio to her overall body weight than a domestic feline. She has powerful legs for pouncing and hitting, and more powerful jaws with larger and sharper teeth. Here ears are still slightly pointed rather than rounded like in most larger cats and her sense of smell is slightly enhanced. She also has sharp vision and can detect tiny movements from vibrations in the air with her whiskers and fur. Her tail is longer and becomes increasingly fluffy towards the tip. This helps her better with balance because of her increased weight.
Personality-wise, she's strong and loyal. She loves Jason and protects him to the best of her ability. She was introduced to Jason when he was around 8 years of age and when she was a kitten. [In the present time of the story, Jason is 18, so that'd make Shadow around 10 years, but because of her mutation she's still seemingly young and not old at all]. Although Shadow seems younger than her age says, she's extremely intelligent, wise, and mature. Although, when she's hanging around Jason, she's playful and acts silly.
That's all I'm going to explain :3 Hope you guys enjoy this character! She's one of my favorite animal charries that I made up X3
