Some people don’t like the idea of adopting rescue animals, especially adult ones. They worry that they won’t be as trainable as a puppy or kitten — they might have all kinds of behavioral issues and odd quirks from their past home(s).
To be perfectly honest, I’m pretty sure Kiko and Pye were normal before we got them. (At least, I’m reasonably certain that Pye didn’t throw noisy tantrums if you neglected to sit next to him and eat cereal in the morning.)
I don’t know how Kiko could’ve survived otherwise. Her history indicates she was an outdoor cat — undersized, post-partum, a hair’s breadth from losing a leg to gangrene. Now, she taps my forehead to wake me up to watch her eat, will only drink out of a special pink teacup, requires smooches on the head at exactly 11:30 AM, and knows that the sound of me brushing my teeth means it will shortly be Cuddle Time. She won’t eat cat treats — her preferred snacks are strawberry yogurt and butter lettuce. She doesn’t like to walk through the apartment, either — she’ll launch herself face-first at my ankles, cry and hold up a paw as if she’s injured, and make big, sad eyes at me until I pick her up.

Her favorite thing, though, is the exercise bike.
I have a bog-standard stationary bike ever since my cardiologist recommended that I start taking short, easy rides to rebuild my endurance. I don’t know how, and I don’t know when, but Kiko made up her macadamia-sized mind that This Was an Activity of Buddies.
And so, she chubbles.
She sits at the edge of the bed, gazing up at me with her cartoonishly large, round eyes. She knows she has me wrapped around her little white paws, and all she has to do is wait patiently. If I fail to respond, she daintily taps at my knee.

Eventually, I will have to pick her up.
I always do.
I have no idea what she gets out of this. It’s a stationary bike. We don’t go anywhere. There is nothing to see but the bedroom door. She nestles herself into my elbow, flops her head back to mush her face on mine and give me her little :3 smile, and purrs. And she’ll stay like that until I’m done pedaling.

There’s no reason for it. She could be ignoring me, happily cuddling with my partner. The second she hears the telltale boop of my exercise tracker app, she pries herself away to chubble at me. She could be asleep, she’ll wake up. She could be in a different room, I’ll hear the strawberry bell on her collar jingling as she hurries from wherever she’s been hiding. She cannot get enough of turning me into some kind of incredibly inefficient one-person palanquin.
So, yes. Sometimes, when you adopt an older animal, they can be a little weird. Most of the time, it’s in the best way.
