Q. My two cats (brothers & 4yrs old) are fighting. Sherlock does this blood frighting yell and hiss and goes for cover. Watson is only wanting to play
A. Make sure they both have plenty of toys, scratching posts and places to perch and hide. If they have gotten along until recently, it is worth getting Sherlock checked by your vet to see if there is a medical reason for his behavior change. Make sure to give Watson plenty of attention and playtime with you. He may just have a higher energy level than Sherlock and wants to keep playing when Sherlock does not.
