This place is amazing. We have been several times (we were actually referred there by another vet since the Big Easy has walk-in hours - and we haven't left). We have dogs and cats and they're great with both, especially our little chihuahua that has seizures (they sing to her when they draw blood to help her calm down... she usually ends up howling along though).
Last summer we very sadly had to put one of our cats down. Out of the blue one day he just wasn't breathing right so I ran him to Big Easy - they called the animal hospital for me and sent me right away to get him the best help that I could. They were so compassionate and tried to provide whatever help they could to make the situation better, but when nothing worked and we had to have him put down a few days later (at an animal hospital since it was a Sunday), they sent us a very sweet card when they found out (they always call to check up on how the animals are doing).
I highly recommend the Big Easy for the cleanliness, friendliness of the staff, convenience of walk-in hours, and overall compassion and love for animals displayed by the entire staff.
