Cailet has cancer. It's an extremely aggressive tumor located behind her left eye, and while she is still somewhat perky, she's started 'yelling' at us, which we think is an indication of pain. She saw the kitty oncologist on Wednesday, and the prognosis is not good. Our choices were radiation therapy (which might give us a few more months) and surgical removal, which would be very invasive and (I think) might result in the loss of vision in that eye. We made the decision Weds evening to try and keep her comfortable and see if she might stay with us through December.
Since then... she's become more yelly, she hates her pain medication treatments, she hates the subcutaneous fluid treatments, she can't eat, so we have to force feed her, and... we had the discussion this morning that we're going to call the vet and make the appointment on Monday.
Cailet has been my constant companion since she was 6 weeks old. She has moved 9 times with me, four of those interstate moves. She saw me through a divorce, and through countless bouts of depression. Whenever I needed it, she was there for a cranky cuddle. I have told Brendan that I don't want to be there when they give her the shot, but the odds are good that I'll change my mind, and see my girl into that good night.
When we lost Brianna, she left a hole that was too big to consider feeling. Losing Cailet is going to leave a crater in my heart that I just... can't function with. We will be looking for another fuzzy companion soon, to help Marcus cope, and to help me grieve.
Edit: We take her in at 10:30 tomorrow morning.
