It isn't very relaxed
From what I understand from the discovery channel, the largest cat that has the ability to purr is the Puma or Mountain Lion.
Cats purr for many reasons. They purr when they are content or relaxed, they purr when they are in pain, they purr while eating and female cats sometimes purr while giving birth. Both male and female cats purr. My neutered male cat purrs almost every time I pick him up. If the cat is spayed, obviously pregnancy isn't an issue. If she acts differently in other ways you might take her to the vet to be checked out but otherwise I think the purring is OK.
An adult male cat is called a tom.
It really depends on the type of cat and their personality etc. The mood as well. If a cat is angry with another cat, what will it do? - hiss and snarl. It can purr for affection to another cat.
There is no illness that causes a cat to purr. Cats purr when they are happy, content, and socialized. This includes non domesticated cats.
