One cat is left to be spayed and moonandbean is donating for that cat. Fleas seem to be the issue at this point. I know how serious it can be. One year I had a room in my house that if you walked into the room tons of fleas would jump on your legs. I have never had this many cats before so I can only imagine how bad it could be this summer. Thanks for caring and I would appreciate any flea meds you have that you can spare. I am not sure how much my cats weigh. I am sure they are under 10 pounds though. Thanks for everything. Rebecca
