Wait - you forgot to put a link in to your post showing us how adorable puddles is, lol! (i kid i get the joke)
Like i said, i have pets, but when i'm vacationing i take them to the vet for boarding. You may think your darling is adorable and all, but most pax just find them annoying and a PITA. Its also a health hazard to some pax, who even if they move away from you, are stuck in a recirculated air with them for several hours.
I also do not want to eat with your dog or cat or ferret or what have you sniffing and making pathetic noises about my food.It's unsanitary.
