I did some volunteer work at a cat shelter/adoption agency for a few months, it's a great little place that rescues at-risk kitties from other shelters that would've put them down otherwise. Lots of poop cleaning, but there was some cuddling too - and the little guys were grateful, rubbing up against my leg when I gave them a clean box, haha. I would play some soft music when I worked, and deep down I really hope that I got some of them into Japanese Citypop. Always sad to see my regulars disappear some weeks (we had a list of who was adopted when), but it was still a good feeling since they were finally with a family.
Sadly, I had to stop going since my own cat is extremely territorial and started to attack me when I got home. He began waiting for me at the door, and would barely let me inside - and he's a big cat, too. I tried multiple things, but the scent of other cats was ultimately too distressing for him.
I really hope other places like this exist elsewhere, alternatives that allow animals a safe haven and give them a chance they wouldn't have ever had. Anyway, that's my little story. Hope it's okay!
