Does anyone volunteer at a no kill animal shelter?

i have been volunteering at a no kill cat shelter for the past year and have become very involved in it. i started off as just a cleaner, then i learned how to do the meds, and now i am the editor of the newsletter which is great and all, but i am saddend, the past few weeks we have been losing cats to certain types of cancer, and it seems to be happening more often. it really upsets me because they were perfectly fine, great, beautiful cats. why won't anyone take them home?even if they are older cats they still have alot of luv to give. its just not fair! i think it's that thought that makes me cry the most, the fact that the cats p away in a shelter, not a warm loving home. we volunteers do give them lots of luv and are very dedicated to them, but it's just not the same. i guess this isn't really a question, just a vent, and a request. if you don't have any other animals and you are thinking about getting one, go to a shelter adopt a special needs cat, thoat no 1 else would!
