It's hard not to see the obvious similarities.
My cat is a little over 10 years old now. He's always been an indoor cat. If you take him outside, he will immediately run for cover. If the door to the house is open, he will dash inside.
Recently he has become slightly more bold, going a foot or two out the door if you hold it open long enough. Each trip is slightly, slightly farther than the previous. The slightest noise, or the slightest movement by anyone or anything, and the cat immediately turns tail and is inside.
One other change of late is due to his pair of pet boys being gone a lot of the time. The cat is more likely to notice when the humans are gone, and much, much more likely to come up and ask to be petted. As the cat's social circle declines he becomes much more desperate for attention.
Given that humans have better medical treatment, I think it would be fair to say that a little over 10 in cat years is about the same as, let's say, 39 in human years.
By the way, my cat's name is Picasso.
My name is Vince.
