Cats' body clock
Do cats have a night/day body clock?
One of our cats, Gemma, always follows us at bedtime, and hangs around for a few minutes, then says cheerio until morning.
And 5 mins before the alarm goes off in the morning, she generally jumps up on to the bed and says hello.
But if I go upstairs at, say, 6 in the evening when I get back from work, she will follow me into the bedroom, as if she thinks it's bedtime.
I know that cats are creatures of habit, but do they know when it's middle of night/ middle of day etc etc? Do they have any concept of time?
