Welcome to the forum
I'm also confused by the mention of outside too - a c&c cage is not suitable as outside housing as they are not secure.
Also, outside living in Florida is unsafe due to the weather, heat and predators.
I cannot see any/enough hay in the picture?
I can see a little hay rack but hay racks aren’t really suitable to be used as they don’t hold enough and prevent piggies from properly being able to play in the hay or get inside thee hay to freely forage. We recommend a large pile of hay loose on the floor or even several large piles (in your cage I’d recommend a hay pile takes up half to all of that end of the cage or even fully fill that top level of the cage with hay). Hay is enrichment and entertainment as much as it is food.
Is the bedding made of paper or is it a fluff?
It looks a bit fluffy but it might just be the picture. If it is fluffy bedding (rather than paper bedding) then it is unsafe bedding for guinea pigs and should be removed straight away.
Either wood shavings, paper bedding or fleece should be used (again with large hay piles).
I would also say that there isn’t much enrichment either. She needs lots of hides and tunnels, cardboard boxes with holes cut in. loose hay piles where you can hide her veg so she can freely forage. I would completely remove that blue cage base on the bottom level and add lots of tunnels and boxes in that space for her to play in. Piggies naturally spend hours searching for food so recreating that is important.
We also do not recommend the use of food bowls for the same reasons - eating from a bowl takes away any opportunity to use their minds to forage, so we recommend you scatter her pellets either into an hay pile or around the cage to get her moving and searching for food. Remembering she can have just one tablespoon of pellets per day (never left with constant access to pellets due to them being the least healthy part of the diet).
Essentially she needs a lot more in there to keep her mind occupied. Mental stimulation and enrichment will be even more important for her given it sounds like she is being kept alone.
It would be best if you can get her a friend - piggies are highly social and should always be kept in pairs. Human interaction, I’m afraid, isn’t enough.
