Thanks for the quick response. She is a really picky eater. My male eats everything. We've tried different hays, Alfalfa, Timothy, Botanical - the botanical seemed to be working for a while and now she's lost interest in it. All of them were the Oxbow brand. I've bought the timothy cubes of hay, no luck there either. She doesn't like rose hips when we give those as treats, so she gets a couple of oats. The list goes on and on. Poor girl is so spoiled, yet she doesn't know it.
She is given 1.5 to 2 Tablespoons of food a day, but typically only eats about 1 Tablespoon of it. I try to never let the bowl be empty, I fill it every evening before I go to bed. If it's empty by morning, it gets filled then too. So she is free fed. My male eats 2+ Tablespoons. I use the Tablespoon to scoop the food so I know about how much they are eating, and always give them more than what I know they eat.
She's never used her pumice block, or lava ledge to chew on. As far as hanging toys, She has a spindle of ~6 Apple sticks that gets replenished about once a month (probably not often enough). I've tried coconut shells, different toys with loofah, and she never nibbles them - they end up in my male's cage. She recently got an arched
bridge thing that we use as a house and put her chinchiller under. She hasn't nibbled this either. If it were in Gizmo's cage, it'd be about 1/2 gone lol.
I'll start weighing her tonight and keep track weekly for a while. I'll buy her a different hanging toy and pick up a different brand of hay. Are there any other varieties/brands out there that you recommend?
