Can I keep owl ornaments at home?

Actually, it depends on your own personal hobbies. If you have a soft spot for this thing, it's ok. After all, this is your favorite thing. Say something unscientific, and what you like will definitely communicate with your heart. But if you don't like it, I suggest you don't decorate it. If it is a late renovation, others will, and neighbors will make irresponsible remarks. What happens in the future will be said to be a disaster brought about by this unfortunate incident. So it depends on how you handle it. I hope my words will make you sound less confused.
