Picards is good would be my second choice after Doc Jacksons. As for animal oils I doubt that using animal oils on leather is going to hurt them. The idea is to restore some of the natural oils back into the leather that is what Doc JAckson's does it is a combination of animal oils and enolients to restore the leather I have used it on Civil War leather and it did a fantastic job in restoring flexibilty to 130 year old leather. Any product that does this is going to work use what ever you can find. Just remeber that some are better than others. I have been working with leather for a few years and have tried them all I perfer Doc Jcksons as it does not leave the leather with the oil feel.
