So today on my way to college I saw a cat that looked ill (didn't look properly but looked like it had gunky eyes) that came up to me constantly meowing (quite 'hoarsely' for a cat meow). He/she didn't have a collar, I've never seen the cat before either. Obviously now I wish I had taken a closer look, but I had an exam in 10 minutes when I was walking so I didn't really have much time to stop. What should I do if i see it again? Even if it's not a stray, the owner should surely be treating the cat. I have no means of doing much really since I'm unsure whether it's a feral cat or not, and I'm probably worrying over nothing (I've seen a ton of rescue cat videos where the cat has been ill).
