(I realized that some have mixed feelings on cat videos or taping bathing cats for youtube. This isn't about that.)
Anytime there is an image or video of a cat being bathed, there is the always a comment or two that bathing cats is unnecessary or even animal abuse.
While cats have the natural tools to bathe themselves, there are countless situations where they need to be helped out.
ASPCA has an entire article about the ideal way to bathe a cat that notes:
With her built-in grooming tools (tongue and teeth, of course), your fastidious feline is well-equipped to tackle her own haircare needs. But if she is very dirty or gets into something sticky or smelly, you may need to give her a bath.
Unfortunately, the article fails to note that those are not the only times someone has to bathe a cat. Illness, age, trauma, breed, and etc often require people to give extra care to cats that often require bathing. Also some weirdos like water! I have multiple friends who were recommended by their vet to give baths to their cats for such reasons and even one that has a cat that she has to lock out of the bathroom because he is always trying to get into the tub or sink. I've been lucky enough to only have to wipe my cat's butt multiple times a day when her mouth was in too much pain. But I guess we are all doing unnecessary things/abusing our beloved pets.
I'm sorry for the preachy post but I'm seriously tired of these ill informed sanctimonious posts that get a ton of recs.
