The cat bath thing exists in Japan. I've seen them before :/ Pets in Japan are treated like children bc of the low birth rate and high cost of living or something. Treating these animals like humans causes way more than enough behavioral problems and is completely biserk and unnecessary :(
My cousin works at a vet and had one of her cat's ears tattooed with a pic of a bunny. She claims it was for id but she has like a hundred other cats without tattoos. It was a gimmick and now the cat looks foolish.
I agree, the website seems to have a cult following but it's all a joke. Some of the pics are real, some are photoshopped. Brings to mind, there is a doggy spa here in my city who dies fur and paints nails. They were exhibiting a chihuahua and a standard poodle at the Pet Expo last year. I guess people think it's cute. I thought it looked ridiculous. If it doesn't benefit the purpose of the animal then you don't need it. A scarf will suffice, and is way cheaper!!! lol On the other hand, if the dog is not harmed or annoyed or uncomfortable or inconvenienced in any way and the human has a twisted mind and disposable cash, then fine. Do it. But you'll be getting harsh words from people :P
