Bom dia Geyda!
Holy crap, Colmar looks like something straight from a fairytale. Gorgeous. I would love to come and visit. I'm now in London, so France is just across the canal. I don't own a driver's license + generally dislike big crowds so biking in a quiet French countryside sounds pretty good. I also happen to own two legs so walking is an option as well.
I wish your street animal project goes well, you should absolutely go for it! I think they will be happy to live freely in their own place with a lot of nature. In Chile there were 2 local students in Santiago who tied balloons on street dogs, so people would notice them better and that cars would not run over the dogs. The project became very popular in Chile.
When I lived there, I used to go feed this street dog at a metro entrance. It's like every dogs has their "own" place there and dogs there also move around the city in dog "gangs". I bought a water cup for him because it gets hot there during the summer and also I gave him the best the dog food I could find. He seemed happy whenever we met. Although pretty sleepy. He was always taking a nap.
Oh, I also saw the "Kedi" documentary a while ago about the street cats in Istanbul, that was very interesting. Istanbul is absolutely one of those cities I want to see and experience in my lifetime.
Okay that's it, I have to go. All the best Geyda, take care! Talk to you soon.
