I wrote that cause I'm one of them, as described on the site as well. I'm in plenty of pet owner groups and the general consensus is that we're all crazy for our pets and probably a little crazy in general, ya. Otherwise you wouldn't spend your time and money on sending your pets images on virtual adventures. And again, I am totally one of them, I spent money and a lot of time on making up adventures for my goat. It's fun being a little crazy ;) People get offended about everything nowadays, I just let them.
"extremely enthusiastic" is a perfectly valid and commonly used definition of the word "crazy". OP shouldn't use it because there might be some people who might inexplicably interpret them as deriding people with serious mental issues? I think it is far from a foregone conclusion that it's inadvisable for OP to use the word.
I have cats. Others have children, but I have cats. And if there's a single "theme" of the photos on my iPhone, it's my cats.
The iPhone every now and then crawls through my photos and spits out a movie with some music based on what it finds. It did a very nice one of my anniversary trip to San Diego with my wife.
That said, I get several "Pet Friends" movies.
I ADORE these. They always brighten my day when one of those shows up. Especially when they make one of my long past pets. It's the same photos as always, as I've always seen, but it puts them in a new light. It's a great feature.
I'm sure someone, somewhere, in some meeting, said "Hey, when we do these movies, we should be able to do ones with pets." And they were right. They should have, and they did, and I'm grateful for it.
