We've had rescues come in with retained shed and caps. The worst one had about 5 layers of caps on one eye...what a mess. I phoned Adam and he assured us with some soaking and proper care thereafter she'd get them off herself. About 2 days came off in the intial soak and the other layers came off over the next two shed cycles. We couldn't believe it but there were two bright, lovely eyes under all that mess.
