When our cat would not eat it was just over $1K for blood work , knockout juice (he's almost rabid at the vet- hates it) and the meds to get him straight.
Wife's car was $1,400 for new breaks/rotors/oil change and transmission service. Unfortunately you have to maintain vehicles or they will let you down. Did you look and see if that pothole drove part of the sheet metal of the car onto your tire, that would make it do all of that?
