I've had a Giant Day Gecko for about 12 to 14 years now. (I need to find the receipt to check.)
I can sit and watch her watching me for ages and she's a great amusing pet.
I'll add some photos.
She's a cracker and still going strong although she can't climb anymore as she has a build up of skin on her feet and can't grip anything.
I'll post this somewhere to get some feedback and a possible solution.
Cheers.
