Does anyone else find that their tort will only eat cuttlebone if it is very weathered? I heard somewhere that they don't like it when new because of the fishy smell. I have two pieces in Boris's indoor enclosure that sat outside for about a month, but he hasn't touched them. Then I put him in his outdoor enclosure on the weekend and there was a horrible old piece of cuttlebone left over from last year -- all green with mould and dirty -- and he devoured the whole thing in about fifteen minutes (he does have limestone flour sprinkled on his food every other day, alternating with Joe's TNT supplement, so he's not lacking in calcium.
