they both look really nice! i'll add to the concensus, too, and say that i don't think they look too old. really old torts look more worn and such on their shells... "timmy" the tortoise (check the link below for timmy info) comes to mind; i saw him not long ago on a pbs show about turtles and tort that had clips from when he was alive, and he really did look the part of the geezer... his shell was battered-looking, and his head even did that kind of shaky thing like old people do.
what i mainly feed my redfoot is spring salad mix (it's a good mix of greens, i think) with an added fruit or some such (i rotate between things like strawberries, blueberries, mango, plum, kiwi, etc.). i've not given him cat food or pinkies, but i sometimes give him a little bit of boiled egg, tofu, or cooked meat as a treat for protein. for supplementation, i go with the recommendation of the breeder i purchased him from, and i sprinkle a pinch of herptivite vitamins and rep-cal calcium on every third meal or so.
good luck with your lovely ladies, and keep us posted if you get any eggs/hatchlings!
