Hi Rebecca, it sounds like you have a good plan set in place. I'm so glad that someone has offered some help to you and that you have 100.00 of your own money to go towards this.
I too would like to send a donation to the vet where you are having them fixed. As mentioned before, I don't have alot right now but I really want to contribute something because you obviously love these cats and want to stop the cycle.
Would it be okay with you if I cross posted this thread in the 'cat general' section? It might be that not everyone has seen this thread and perhaps we can generate some help towards getting your cats spayed and neutered via donations.
Could you PM me the name and address of the vet clinic you will be using? Then I will send something to them on Monday morning. And if anyone else on PT is interested in helping, could they PM you for that info too?
