Help with digi legs?

I've looked through a lot of tutorials but I'm still really unsure as to how to attach fur to the legs? Do I glue it on the padding or do I sew the tights the padding is on the to the fur and glue the fur in certain places to help keep its shape? Also is it a good idea to have the feet attached to the legs or to keep them separate and how should I fur where the two meet if separate? The feet are a bit heavy so I'm worried the foam will rip. Also if you guys have any input on the shape of the legs themselves that would be cool too, they're not quite animal-like yet? And if the feet stay separate from the legs how would I position foam where they meet so it doesn't look funky? Cause right now it's really obvious where they separate.
