Although I am not a person who loves pets due to allergies to their furs/hairs and etc. I think there are people who are willing to spend a significant amount of money on their pets because they feel the need to. They treat those animals like humans and not only that, they are their loved ones.
Having said so, people like them do not actually care about money anymore. They can spend plenty of their finances on such animals regardless of their breed as what is important for them is to care for their pets as long as they can and show their love for them.
There is a saying that goes, you cannot bring the things that you have when you die that is why those people I guess are just living their lives to the fullest. If having pets make them fulfill their duties here on Earth then I guess that is where they found happiness. I know someone who has lots of cats at home and they are just stray cats, those cats are everywhere, from her kitchen to the dining table and etc. It might look nasty for me but for her it is a good thing.
