Angel isn't very rambunctious, but Simba is. He's a little character. Simba is about as naughty as a kitty can get, but he's so cute in his naughtiness, I just can't get mad at him. If Angel wouldn't react to him, he'd leave her alone, but as long as she reacts, he seems to have fun getting a rise out of her. He does it to Shane all the time, because Shane over reacts to Simba trying to play with him. Angel is really scared of him, so she reacts, by hissing growling and screeching at him, and all he wants to do is go back for more. SunLee is more Simba's equal, which surprised me. She chases Simba around the house, and pounces on him, which he loves. The two of them go back and forth chasing each other, and SunLee just LOVES Simba. I'm hoping Angel can find her kitty soulmate in Shane.
