I have decided to not opt for additional man made formula for Tinker and keep her going on fruits and youghurt including dried fruits occasionally as I met a friend whose glider is six years old and totally healthy and only needs to go to the vet for nail clipping. He gives veggies on a wile as he believes every over the counter food has some sort of perservative and a sugar glider does not get vitamin supplements or over the counter food in the jungle. He told us when he got his baby, he did not even know how to use the internet and gave all natural and did not give any extras and believe me, she looks good and active with beautiful skin and still the same colouring. He has only one glider and after 6 years, she has not self mutilated so having seen a healthy glider personally, I have decided to follow a guy who managed to keep his pet healthy without over the counter food or supplements.
