Cat may have ingested paint?

I'm not sure, but I think my cat may have had a lick or two off his fur of Benjamin Moore paint. Immediately after he stepped in it, I took him to the bathroom and washed him with shampoo and water. I got most of it off, but I can't help feeling that he possibly got a lick of it before I washed him or perhaps there was some left on. He is definitely more sluggish than usual and was hiding from me. This could feasibly be because he's scared of me picking him up and taking him back to the bathtub(he HATES water of any sort unless its for drinking) but I'm not sure if it's a symptom of poisoing. Vets are closed now, so there is not much I can do. He is eating and drinking, which I guess is a good sign. Does anyone have any advice or opinions on whether he actually conumed a harmful amount of paint? Thank you
