I have two cats who living together for almost 10 years without any major fights. They are both neutered male, one is 10 years old and the other is 11. Both should be healthy since I just get their senior screening done last month and everything's normal. They usually eat together, play together and sleep together.
Today all of a sudden the younger cat (very shy) start chasing the older guy(social King) and beat him down really hard - they hiss at each other, yell badly and fur flies everywhere. I separated them but after a while they start to fight again. It's been at least 5 rounds this afternoon. Now the older cat is hiding at the corner under the bed and the other is just waiting there. Both of them refused me touch them or pet them(usually they are sweet boys and just purr ). Anything I need to worry about? Do I need to reintroduce them after living together for 10 years :-? I tried to feed them some treat they crazy about but both don't come to me now.
