Clyde and Scooter were both neutered about 2 years ago.
The funny thing is today they are getting along better than they have in about 6 months.
I think that Scooter might just be jealous of Clyde. Scooter isn't really a cuddly cat, but Clyde is, and Clyde is always trying to sit on me or lay next to me when we sleep. It could be that Scooter is jealous of this.
