I have 5 redfoots. you dont get certs with them. You need a big table for the with deep substrait that needs to stay damp.How old is your son as a redfoot is the last thing id ever buy for a child. Thay may not be the hardest tort to care for but thay are not easy and thay do get very big. As adults thay will need a heated outside home and thay will need to be kept warm all yr. My reds have doubled my electric bill Also my last vets bill was £210. Alison
