Gave my cat a bath and now he's acting weird

so my cat is about 13 years old or so.. I gave him a bath last night, it was weird usually he licks himself after but he just sat there. Then later that night he was running down the hat and ran right into the wall then started walking sideways :( then this morning I found a few spots of throw up mostly cat food but I have another cat so it could have been the other one. So I started thinking maybe I didn't get all the shampoo off it was a flea and tick shampoo and he doesn't have fleas but it's all we had I know I had gotten all of it off his back I just fear maybe I didn't get his stomach well I don know why he's acting so weird

Hi
Well at 13 he may be suffering from an age related illness such as senility which may have been made worse by the upset of the bath (cats don't like baths very much).
As you say the other possibility is that he ingested some of the shampoo which has caused problems..

In my opinion if he is still the same today i would definitely get him to a vet sooner rather than later in case he has poisoned himself.

I hope he is Ok again soon

best wishes Kate
