buy a troutty camera (check second hand places for a less troutty camera at a troutty camera price) and learn about photography and how to take good photos or you'll be one of those people who buy a $$$$ camera and use the Auto function to take pics of their pets

then when you get good at cameras or you haven't decided it was a dumb temporary hobby (90% of people who buy a camera) then you can buy a $$$$ camera that you wont leave to gather dust except on birthdays or when your pet does a funny thing hope this helps
