Old - er - MATURE cats are a lot of fun. My two are 16, but don't tell them! Especially the female, Mimi, still acts like a kitten. The other day she brought us a bird (gee, thanks!) after several years of catching nothing faster than slugs (the big Westcoast ones - yuck). But her main job in life is to glare at the dog and keep him in a perpetual state of terror.
Her brother, Grumpy, is getting lazy but not when food is involved. He's having a bit of a nervous breakdown right now because he's used to get his dinner at 5pm sharp. The change from daylight savings to standard time has always been hard on him. (They do have dry food to nibble on all day but dinner is special because it comes from a can.) His relationship with the dog is a bit more relaxed, from ignoring him and walking underneath his belly to actually making playful advances.
The dog is a lab/husky cross; lovely personality, too smart for his own good and usually scared spitless of Mimi. Every once in a while he gets some kind of death wish and starts barking at her, jumping around and making play bows. Her response ranks from totally ignoring him to the iciest glare you ever saw to physical retaliation. I sometimes hear his playful bark, followed by a hiss and a yelp, and by the time I get to the scene I find a cowering dog and a cat stalking past me in high dudgeon.
On the whole though they stick together, united against the humans, and unlike little kids they never rat each other out! We have found evidence of feline-canine joint attacks on the garbage or leftovers (and sometimes they don't wait for the leftovers - that's why we now have a kitchen door.)
I'm in good shape. Round is a perfect shape!
