Last night I stupidly washed a car oil patch on the back of my cats neck with undiluted Fairy washing up liquid. Not only that but because he was trying to get away from me while doing this, the detergent was not washed off properly. He was also wearing a new flea collar at the time. This morning my husband woke me to come and look at the cat and it looked like he was having a bit of a fit. I have since washed the area throughly, have given him an arnica tablet and waited for half hour. He is still twitching periodically and has since had another (I think) fit. I have washed the area again (which feels warm to the touch) with aloe vera wash and put some aloe vera gelly on. PLEASE can somebody help me. I am beside myself. I have left him on one of the beds but everytime I walk in, he seems to want to try to get up. Very unsteady on his feet.
