Cat Vet Bill

Ok so.. She is 16 years old and in perfect health except for some kind of mass in her GI tract. She has gone from 10LBS down to 6. The blood work and the other tests were 330 and now the ultrasound will be another 300 plus if the need to extract some for testing. We love her with all our hearts and do not wish anything to happen to her ever.  I do not work because I have mental health issues and my partner works way overtime just to pay rent and well the 330 recently and we will do anything for her. So if anyone can or wants to help that would be greatly appreciated
