when i got home this evening, around 11:30, I found a cat sitting at my front door. i brought him/her inside and gave him/her some milk and chicken and removed burs from the fur. this cat obviously belongs to someone because it's very friendly, clean, and was wearing a collar. i put it outside and went to see if it was still there about 45 minutes later and it was still there, so i put out a bowl of milk and a rug for it. i figure it'll go home soon, but what should i do if it's still there tomorrow morning? my apt complex is a no pets allowed place, so keeping the kitty isn't an option. suggestions?
