Cat isn't recovering, please help fund (CW: euthanasia)

Even after several days of antibiotics and I.V. fluids and appetite stimulants, Dottie isn't doing well. She can barely move, and won't bother to eat or drink even if it's right next to her.

We don't want her to suffer, but euthanasia is apparently something we have to set up an appointment for, and pay extra to get the body disposed of afterwards. We're barely holding on ourselves, this has us so dissociative that we aren't eating either.

The cheapest we can find is asking $300 for euthanasia and cremation. Anything helps. Thanks.
