Help barn kittens

Hi, my name is Nancy. The last few years I've been taking in and fostering barn kittens. What started out with 1 litter here or there, turned in to 47 kittens last year. So far I had 2 litters in January and I'm expecting a litter of 6 1st week in april and 2 more litters who haven't been born yet. I make sure they are treated with flea meds, dewormer, and ear mites. Some are wild and need extra snuggles. 4 came last year that needed medical attention asap. I can afford the food, litter and toys. It's the emergency room visits I can't afford. I would like to raise enough funds to have on hand just incase any kittens need to have medical attention. Any donation would be greatly appreciated to help save a kitten.
