Welcome Alicia and Juliet.
I agree with Voula that you can start the low carb canned food straight away.
My cat Sheba has arthritis and she also had peripheral neuropathy in her back legs. Her back legs were very weak and she could not jump up onto chairs and her legs would slide from under her. I started her on Zobaline for cats and over time and with improvement in her diabetic numbers- she is now back to normal and can jump up on chairs etc.
Here is the site to order Zobaline.

Do you know what insulin you will be using? One of the long lasting insulins is best-Lantus or levemir. Pro zinc/PZI is also good but I know nothing about this insulin.
Can you tell us what country you live in as every country has different things/ names etc
Probably one of the best things you could do for Juliet,apart from low carb wet food is to get a glucose monitor and learn how to take her blood sugar levels. You will save a lot on vet bills by doing that and the wonderful people here will help you with dosing. It will be much safer for Juliet if you are monitoring her numbers.
Can you click on your profile and go to the information tab and in that is your signature. In that you can list Juliets age, insulin if known, country you live in and food. Later you can add other info. That will then appear at the bottom of your post.
Don't even think about putting Juliet down. Diabetes is a very treatable disease and the people here will help you with ideas to keep costs down. As far as I know, I think blood clots would come on suddenly and they are very painful....not like arthritis but acutely painful so I doubt it would be that. To me,it sounds like she has peripheral neuropathy. And as I said.... It can look really bad but it does get better.
We have many cats here that have been successfully treated for diabetes.. Some are even able to come off the insulin in time.
I know how stressful this must be for you....it is always hard in the beginning, but it will soon become old hat!
