For Toby's Veterinarian bill

I have been able to handle Toby's vet bills up until now.  He is currently in the Veterinary Emergency and Specialty Hospital of Wichita with another outbreak of ketoacidosis.  This is REALLY bad timing because Toby's usual veterinary is closed until January 4th and my backup veterinary is also closed until Monday.  My only choice for care is here at the emergency hospital.  Right now they are saying $2,700 but that could go higher.  I can cover some of this unexpected expense, but I need help with the rest.  I am not at the point yet to put Toby down.  He's my buddy.  He's my family.  Please help.
