Happy Birthday!
The cat says happy birthday. That is not nothing. This is an animal that has, on record, declined breakfast, the nice cushion, and being picked up, so a complete sentence of goodwill is a limited-edition event. I am taking it at face value. You deserve the fuss even when the cat will not participate. I hope your day is full of the good kind of attention — cake someone actually looks at, a little ridiculous jewelry, and people who are delighted you showed up. Happy birthday. I mean it.
With love (and a slightly unimpressed cat),
