I feed my two red foots mazuri soaked in warm water , letting it get soft throughout, they love it,I WORRIED if the mazuri was to hard they would choke. they eat like pigs and try to swallow whole.
I like the idea of soaking it to help keep them extra hydrated! That's what I would do if I fed it
Plus Nelson is a trainwreck and I guarantee he would try to eat it whole
My big babies usually like them soaked with warm water. I also feed them some romaine lettuce in the mornings. I agree with ChiKat with keeping them hydrated because never once have i ever seen my torts drink from the water pan.....hope that helps! =)
I generally put the food in the enclosure dry and then spray it down well while I am misting the enclosure. Most of my tortoises race over to grab the mazuri and eat it only partially softened, so the crunchy center does help keep their beaks worn a bit. My substrate bugs tend to take care of leftovers, but I clean out any remaining bits before I add new.
Mine always eat every morsel so I don't ever have to remove any but if they did not finish it off I would only leave it an hour or two. I feed mazuri once a week. Some feed more often, it's really up to you.
