Stray Cats and Kittens

I am desperately writing to raise funds for some stray cats and kittens in my area we are trying to get fixed or find home for if we are able to socialize. There are about 3-4 older kittens I would like to try and socialize and one white momma cat who has an injury to her tail and it keeps getting shorter! We have already lost 2 kittens who disappeared a few weeks ago, and another kitten was just hit in the road the other day. Unfortunately, we are at capacity 9 inside cats a d struggling ourselves to care for the ones we own. Taking on vet care (spay/neuter), vaccines, dewormer, litter and food isn't something we can afford. Over the past 4 years we have already trapped, fixed and adopted or relocated 20+ cats in my area. The last injured cat we had for a year and a half before we found his purrrfect home and his initial vet cost surpassed $3,000 due to some serious injuries and he also had FIV. We have spent so much money trying to help keep the cat population down and it just seems to have gotten out of control once again....the only thing holding me back is cost, cost, cost.... I have the heart, I can make the time, I just need support in order to help these cats and kittens
