Whenever Teddy's head looks dry I take some warm water in a cup
and using my finger or thumb I just dab some onto his head. He
likes it and it (my opinion) gets him very used to having his
head petted. He arches his head up and strains to have it petted
which is funny when people are watching, they're so amazed at
how friendly he is. You can also (a little bit cause yours is still
tiny), get him used to petting his neck and legs, they usually
like having their neck rubbed.
The best substrate in my opinion is lizard litter kenaf plant
variety, which I also buy sold as "Life Mate" for small animals.
I used it when he was tiny and still do. Get away from the pellets
because in addition to being moldy, they offer poor traction
for walking and adequate leg muscle development. It's like
walking on a shifting surface constantly. Good pics. niki
