Don't piss off a cat.
I've learned this lesson many times in the past few years. But it never sticks. Mainly because I don't actually know how to actively piss off a cat. I just happen to do it on a regular basis.
Kay, my "responsible" cat, never really seems to stew for very long. He just kinda accepts that he's been pissed off, then hides somewhere until he calms down.
Sagremor, on the other hand. Well... he's a bit more stubborn. He's also a bit more clingy, even though Kay is the one who likes to follow me around like a puppy.
I typically let both cats outside in the morning. It's part of the daily routine. I get up, go to the bathroom, let the two cats and one dog out of the house, then go about making breakfast, getting dressed, etc. Kay is great. He goes out, plays outside damn near all day, and only comes home when he wants to eat dinner and go to sleep. Basically, he's out, then in, and that's it.
Sagremor... ugh. He likes to go out, come back in, go back out, come back in, go back out, come back in, go back out... yeah... ugh.
One night this last Halloween weekend, I had guests. Sagremor went out, came in, went out, came in, went out, came in... It got kinda irritating. After everyone else was gone (sometime just before 2:00 AM on Saturday), I'm doing my habitual last email check before bed (yes, I'd been sleeping at that point). I hear Sagremor meow outside of the window. Usually, this means he's ready to come in, eat, and fall asleep. So I let him in. And then I went to bed.
Or tried to, anyway, since he decided to meow incessantly in a futile attempt to be let back outside. Sorry, dude, but I was comfortable and teetering on the edge of an all-too-rare-these-days passing-out sleep.
The next morning I'm feeling quite refreshed. I get up, use the bathroom, and let the animals outside (except for Kay, who continued to sleep for most of the morning). And that's when I see it. A piss stain on the carpet. That big "fuck you" that only a cat is capable of.
Fine. Whatever. I clean it up. Since I was cleaning already, I decided to do a complete run-through of the entire house. Bathroom. Kitchen. Vacuum. And, shit, since I was well-rested, I decided to vacuum the couch and fit it for a couch cover. Removing the three cushions, that's when I see it. Or them, rather. Piss stains all along the backing of the couch.
They're clean now. The couch is covered now. And I'm calm now. But Sagremor is very lucky he was outside.
