I poured an entire bottle of mouthwash down the sink as it was expired, ran a little water to get rid of the smell, but it was still there. So my cat, who is just over 1, must have been enticed by the smell and started licking the sink. I think I'm being pretty paranoid here, but dont want to be too careful. Is there any chance he could have actually ingested anythjng/a harmful amount?
