This cat was in our garage when we woke up and then we left for a couple hours and came back and it was still there and it kept meowing so we gave it some milk. Then it still kept meowing so I sat outside and played with it for a while. It wanted to go inside really bad then so I left it alone outside because i wasnt sure what disease it might have or maybe ticks/ fleas because it keeps scratching itself. Now it’s been two hours since I left it alone and its still sitting by the door meowing every time I walk by. It won’t leave, so what do I do? Take it to a vet?
