You can't tell me what to

oh, a pretty cat!

If toxoplasmosis reduces my heart attack risk and stress with no discernable side effects sign me up!

toxoplasmosis saw all the microbes in our gut living in harmony and wondered why the fuck everything else isn't doing that, hell yeah let's just make the humans feel happy and they'll ensure our survival FOREVER

So what you are saying is the more cats I get the richer I will be?

Isn't it also that pet owners in general have better health?

Some cats are grade A dingdongs!

Still love them all.

Depends on the cats personality, some will tolerate, others will kill.

Yup

Depends on the cat. There's some that will let you do just about anything and at most bat you with a paw, claws retracted. Then there's others that if you don't pay attention and pet them just a fraction wrong will take your arm off. Know your cat.

Survivorship bias: those who live through the encounter have lowered stress.😁

according to Google, cat purrs are at a specific frequency that somehow helps you heal faster

One of it's purrrposes is to shake wounds and increase bloodflow. This is why cats sometimes pur after conflict; they're licking their wounds in multiple ways.

afaik the notable thing is actually that the purrs help heal bone fractures, which is presumably something to do with vibrations helping the process along mechanically somehow.

But of course there's also just the psychological effect of having a purring cat near you, same thing as how people heal faster from stuff like acupuncture despite the process itself not doing anything, we just benefit from feeling happy and cared for.

Nice, that's basically free healthcare.

normalize communal cats
why should people just have one or two cats when everyone could have 35 cats?

I can answer the second question:
Generally, hot-blooded mammals transform 90% of the energy they get from food into heat.
So using a cat for heating your room is about 90% as effective as burning cat food in an oven.

Here's some napkin math for where I live:
1kg of firewood has 4kWh = 4000 kcal
which is about equivalent to 1kg of really cheap dry cat food (mostly carbohydrates)

1kg of firewood costs about 40 cents
1kg of cheap dry cat food costs about 1,20€

So, cat-based heating is about 3.3x more expensive than burning pre-dried, commercially purchased firewood.
(all of these prices heavily depend on how much you buy in bulk, though. And if you care about your cat's well-being, you're gonna spend 2x more on its food)
