Hi Salty:
How is Kuzia doing, how is his eye, and were you successful in getting a Vet visit arranged?
I'm glad that Kuzia is eating well but I would like to deliver a sort of caution to you in regard to the Zupreem diet! To be honest, I do not have any experience using any of the Zupreem products with my Squirrels but there is a reason for this and that forms the basis for my caution to you! Zupreem makes what may very well be great bird food, Ferret food and food for certain zoo animals but I am not aware of them producing a diet designed for Squirrels, rats, mice or any rodents! Squirrel and closely related rodents such as Rats have special dietary needs and concerns and their dietary requirements differ from those of Ferrets. For one, Ferrets may be omnivores (animals that eat both plants and meat but they are primarily carnivorous. Squirrels may technically be omnivorous as well but they are effectively Herbivores (plant eating).
My recommendation would be to transition Kuzia to a quality RODENT diet such as Teklad 2018 or Mazuri Rat and Mouse Diet or Henry's Healthy Blocks! These are made specifically for rodents and both have had extensive successful utilization as nutritional support for Squirrels! Mazuri Rat and Mouse Diet is available at most pet stores such as PetSmart and from Chewy. The Teklad 2018 is not as a rule available in pet stores but can often be procured at a Feed Store BUT a large bag is all that is available from the manufacturer and can be expensive and end up wasted! I use Teklad 2018 for most of the Squirrels in my care and I have purchased smaller, less expensive, and more manageable quantities from an eBay seller call ecoSandy. I have been buying Teklad Blocks from her for years without any issues. You can order just about any size bag of Teklad Blocks you might want. Here is a link to ecoSandy's eBay page for Teklad 2018. If you are interested, you can take a look at this;

Another option would be to use Henry's Healthy Blocks (HHBs). These are a CONCENTRATED food source specifically formulated for Squirrels! An "average" (NOT a Flyer or Groundhog!) will receive ALL of the necessary Calcium along with ALL other nutritional requirements and recommendations by consuming just two HHBs (about 10 Grams) each day and the MAXIMUM number of HHBs given each day should NOT exceed three. Here is a link to Henry's page for their blocks. Of the options, I would recommend the Picky Blocks; https://henryspets.com/squirrel-blocks/
If using HHBs, you will need other food sources to help you Squirrel feel full. There can be provided by using some Teklad or Mazuri Blocks and/or based upon the Henry's Healthy Food Pyramid where the wide base is the healthiest foods which are quality Blocks and as you move up the pyramid to the tip, the nutritional values go down and at the tip you will find the treats such as nuts and fruits. Yes, for a captive Squirrel, nuts and fruits are treats! All captive Squirrels should have at least 80% of their diet comprised of quality Blocks and any remainder should be comprised of items from the lowere levels of the Pyramid and only rare treats if any at all!

Please keep on with updates about Kuzia!
