And... As a measure to attract more birds, I decided to take some action to kick out wild cats from my backyard and feed some birds.
Feeding birds might be better than feeding cats. Homeless cat wondering around is already causing me a lot of problems. But birds know how to keep a distance with humans and don't steal food from my kitchen.
@trinsec Yeah, but people (mostly tourists) feed the cat just because they think the cat is cute. So the cats reproduced in an out-of-control way, and now it's really hard to capture. And it causes a lot of problems for the local people (mostly stealing meat and fish from someone's kitchen).
And our local government didn't offer something like a free TNR program. Some pet stores offer a special plan for those stray cats, but still not cheap.
