Cancer? Fatty deposit? What do I do?

Hi, I am a cat behavior, and I understand your feelings. All cat lovers had gone through this, and such a hard answer all the time. When my former cat was in this situation, what my partner had done was ask the vet, and be honest with them on the finance. Good vet will work with you on the bill... like finance or payment plan. It cost me around $ 700.00 all together last time for blood test, xray, medicine and until the end. We all love our cats, and sometimes put yourself in their situation? would I want to continue to suffer? Hey my owners had love me, given me a home, and cared for me. So please do not feet guilty, as they understand.... trust me! Spend time talking to them, and you will get an answer from them!
