I should have mentioned that the other emergency clinic, which has, I admit, been here longer, charges no such fee on top, and will do all possible to save pet within the original estimate.
In my case the bill was 500.00 to watch the cat in the cage for 4 hours. They gave no treatment, did no diagnostics. Cat was asthmatic and was mouth breathing. Took him in hoping they could give him inhaler- they wanted 300+ to shoot a chest xray, and would not let me take him home. Finally they agreed to let me take him to the regular vet at 6 am when they opened.
Regular vet shot xrays, found lung abcess, gave antibiotics. Told us cat needed to stay hospitalized, was going to die, etc. I said- there is no more money (spent it on nothing at emergency clinic.) Took cat and antibiotics home. Regular vet cost 200.00.
Cat was eating 3 hours later. Recovered fully.
The older e-vet in town has been wonderful- we had to take beagle for seizures once and for ruptured capillaries in ear once. (swelled up like a water balloon). Both of those visits included diagnostics, treatment, and in the case of the ear, surgery to drain it. Cost under 300 each time. Should have gone there with cat, but I had heard about this fancy new place…
