Oh man, now you’ve got me going!
Firstly, cats stim. They purr, swish their tails and knead their paws against pillows, blankets, and other soft things. Many cats actively seek out sensory experiences, like listening to birds singing, lying in a sunbeam, rolling against the grass, etc.
Cats have sensory sensitivities— many of them dislike walking on certain flooring, touching certain textures, and certain smells or sounds may make them anxious. Their fur is very sensitive, they can sense the lightest touch, or speck of lint, or dust and their skin will quiver until they can lick or rub it off. When they become overstimulated cats retreat into a small, dark place to recover.
Cats love routine. Many cats know the exact time that their owners wake up in the morning and will wake them. A cat with a routine is a happy cat— they love to have their meals or soft food on a schedule and will learn their owner’s schedule. Cats will become anxious when the schedule is disrupted or if their owner doesn’t follow their usual routine.
In the same vein cats are very wary and/or anxious when it comes to the introduction of new things or people into their environment. Cats require time and patience to get used to anything or anyone newly introduced. Cats also feel anxious when existing furniture is rearranged or when a new smell (like an air freshener) is introduced into the home.
Cats often have “special interests”, a particular activity or thing that they love and can spend hours enjoying. It could be playing with a particular toy, chewing on something, listening to the radio, or watching the clothes in the washing machine. My cat Kitty has a certain ball that she fixates on and will happily enjoy and obsess over for hours.
Finally, cats have a very distinct and subtle body language. The difference is particularly evident when compared with the exuberant, unsubtle dog. The slightest twitch of a tail or turn of the ears, the frequency and timing of blinks, and the positioning of the tail in relation to the body are all little movements that can express much. To the untrained eye it may appear as if a cat is bored, aloof, or unaware of its surroundings. But once you learn to recognize cat body language and understand cat communication, you’ll be amazed at the depth of emotion and how expressive your cat really is.
Yes, I think that cats have a lot in common with autistic people. And that’s wonderful!
