At our place of business we feed 3-4 feral cats. We have captured them, actually 6 of them at the time, with an animal shelter supplied humane trap and had them spayed and neutered. One of them suffered a broken tail about a year ago. The piece that was broken fell off, the hair from the broken off part to the body fell out and a scab formed. The scab keeps falling off and re-forming. We can't afford to catch him and get it fixed at a vet. Anyone have any suggestions? Thanks.
