Why do cats always bathe themselves after being petted?

Hmmm. Have to say that I'm not familiar with that behavior. Maybe: some cats when their fur is ruffled will try to groom it back. (??) Mine always groom after eating, if they get wet, or sometimes when they are enjoying a relaxing moment at their leisure. Sounds almost germophobic; but I thought that was only somethings humans could be.

Likely just scent related. Some cats are more concerned about it. Others, with more sensitive skin, will do it to just rearrange their coat and take care of any itch petting may of caused - sort of like how if someone touches with your hair you have to readjusted it even if you're not concerned with them messing up your hair.

I think it is to fix their fur after the petting has mussed it up, and maybe also because of the scent/oils in our hands.

Mine don't always do this. They seem to groom themselves after eating, most often in my experience. Cats are fastidious and this is for many reasons. It maintains health to keep clean plus keeps smells down which in the wild keeps them safe from predators and helps them sneak up on prey.

My long haired Raggie cleans up after I pet her but my short haired colorpoint doesn't.

The shorthaired girl will rub all over me for 5 minutes then trot off to play without washing herself off so I think it's that the long haired beauty queens need to be sure every hair is in place.

I read somewhere it's leftover instinct from when cats were wild. They'd lick off any scent they picked up so predators couldn't suss them out. Or was it so they could sneak up on prey undetected? One or the other.

My semi long haired baby licks herself after we pet her and after eating.

It throws their signature scent off and they don't smell right. Grooming themselves put that scent right and makes them feel easy. Plus, if they live with other cats, not grooming themselves back to their initial scent could promote a fight with another cat.

This is all speculation so I asked Fay but all she'd tell me was "meep".

Since Bella has very long hair I always mess it up with I love on her. I just thought she was a little vain, or trying to remove my cooties

None of mine do that, not even the long haired cats nor does the wildest of the outside cats. Most of them are dedicated to covering my pantlegs with cat hair with all the rubbing they do, and when I pet them, they 'pet' me back with tongues.

This gave me serious giggles. No fair!

Both of mine do this, but not consistently. They do not generally do it if *I* pet them...however, if my parents, grandmother, or sister so much as brush against them, it's bath time. I do share a house with my parents, but the second floor is all my space, and therefore the kitties' space. All their various stuff - food, water, litter boxes, beds, toys, etc - are mingled with my things, and therefore I'd guess that my own scent is transferred heavily to them. They spend 75-80% of their day with me, and always bathe like maniacs after their time downstairs (which smells of my parents and their two slobbery dogs!), or after my mother pets them.

Surprisingly, Sophie will allow Nika (my parents' Malamute/Collie mix) to give her a tongue-bathing, complete with dog drool, and be perfectly content with it. I'm talking literally head-to-toe slobber stripe. She loves it. She will roll around on the floor while Nika bathes her, then rub against the dog's legs to cap it all off. Then she'll go sashaying off with a dog-drool mohawk like it's the latest fashion.

In any case, I lean more towards hissy's theory based on my own experiences with them (the dog slobber being a notable exception to the rule). I have also heard the theory that they are trying to sort of "extend" their petting session by "tasting" our scent after we pet them...but if that's the case, then they really don't like me much.

I have 4 cats but only Manny does this.....and he does it almost 100 perent of the time. I thought it meant" OMG I have human cooties"
