My cat is acting weird.... Is he okay.... (read)?

So my baby (cat) is normal indoor outdoor cat. He does both. Right as I am typei g this it is 12:31 and he usually comes in at 11:30. He is still outside and I can't find the baby. Well today he had a bad day... He got into a cat fight and lost it had a high piched squeal and his fur was everywhere I checked to make sure he was ok.... Also he had a mood swing one second he is purring on my lap the next he is scratching and biting my hand!! He is a good cat but he doesn't aways act like this well I got him inside (thank god) but he still acting weird so is he ok
