http://www.oasisanimalsanctuary.org/ You pay according to the weight of your pet. I sent my application in plus $30.00 for a certificate to get the spay/neutering done for free. They go by your income.
I also spoke to someone today who is very knowledgable in pets and she said that if the lump moves around it isn't cancerous. If it doesn't move then it's a strong possibility it's cancerous. What get's me is why didn't the vet tell me that. Piper's moves around,it is smaller than a pea.
So far she seems fine. Her surgery is set for the end of October.
Thanks for your reply.
