Please help my Daisy recover

My Dear Friends,
Daisy and Morgan, my beloved fur babies, are in trouble. Each has a serious, life-threatening disease. Morgan has Feline Odontoclastic Resorptive Disease, which means, his body is attacking and destroying his teeth and many have to come out. Daisy has chronically inflamed nasal passages, born in February and on the street for 6 months; the vets believe she has a node or nodule in her nose that, as it grows, limits her breathing and presses on her nasal passage causing pain and newly has been diagnosed with diabetes. These diagnostics/procedures and now insulin are quite costly, and time is of the essence. I’m a very worried, single cat mom with lots of health issues of my own, and no resources, I really need your help. I would be grateful beyond words for any help you could give in keeping my babies alive. Thank you.
