When it comes to pricey pets, a select few rule the roost. Exotic birds command top dollar, with Hyacinth Macaws setting you back a cool $15,000. But they’re peanuts compared to Tibetan Mastiffs, the world’s costliest dogs, selling for a whopping $1.6 million. Fancy a feline? Prepare to shell out $100,000 for an Ashera cat. Remember, owning these critters doesn’t come cheap, but their companionship certainly makes up for the price tag.
