Honestly, I got no problems with the rats. They're kinda cute actually.
They have all the money & this part of the city was literally planned IIRC. But yeah, no working sewage.
Wait, are you the one posting all these pro-rat posters? [1]
Twenty years ago, I knew someone who worked for one of the large, upscale department stores, and she said they spent a lot of money and effort to try to control the rats in their elegant but old and porous building—which, like most department stores here, had many food shops in the basement.
In some European cities an area the size of a parking space is a few chutes into an underground dumpster. It moves the trash (and the rats looking for it) out of sight.
Yeah, I know it can be an unpopular opinion, but I've always found them adorable, and after having gerbils in high school it's hard for me not to just think of bigger versions of them (obviously they do have other appearance differences, like the tail having less hair and the snout being more pronounced, but the way they move and act is surprisingly reminiscent of my past pets). Don't get me wrong, I'm not going to try to pet them like I would a domesticated pet rat, but they mostly just hang out in the background and don't seem to have any more desire to approach people than people have to approach them. I suspect that there are public health reasons for wanting to curtail the population, but people seem so disproportionately disgusted by them compared to other public health hazards that it's hard for me not to wonder if the political desire to get rid of them is influenced by that.
