It is really nice knowing there is a 24 hour place open to see my kitty Charlie in case it's an after hours emergency. Of course it is more expensive than your vet, but like I said, this is more after hour emergencies. Staff here is very nice and caring, which means a lot especially for your furry family member.
I will add with some advise. They do a quote for you before they do any treatments. My original charge was going to be $300 range. Woah! I got is down by $150. Now every case is different but they will go over every charge. I asked for the cheapest. That my friends is they same with any animal clinic/hospital/or vet though.
