My name is Mowgli!

We got Mowgli in July of 2022. He was doing great with our other cat, they were best buds. Then one day he attacked our other cat for no reason, bit a chunk out of his tail, and has wanted him dead ever sense and will stop at nothing. We've been keeping them separated since May thothr day, we had our other cat in our bedroom so Mowgli could roam the house freely. Mowgli was by the door to our bedroom. I think he knew our cat was in there. I needed to get in the room so I very gently and slowly tried moving him with my leg and that's all it took. He attacked my foot badly. He figured out it was me soon enough and let up. Other than that, he was very friendly, playful and a relaxed, laid back guy. He really is a great cat. We can't keep doing this, him being in one room most of his life is not good, he needs a home with no pets. Or else I'll have to surrender him and he may have to get euthanized. He's independent, so if someone is gone a lot thatsfine.
