Niles Animal Hospital is a great place. They have taken stellar care of my cats, rats and parrot. They are one of the few places that actually has the training to treat birds and other small mammals. Since my parrot is 24, he needs a good vet who knows their stuff.
It is true that they are not open in the evening but they do open very early in the morning, so it would pretty easy to take a pet there before you went to work. And they have been great about any emergencies we have had and seen all our pets pronto.
Dr. Sakas is probably the most experienced avian vet in Chicago and maybe even in the Midwest, so if you have a bird, this is the place to go. Since they were so good with our rats and bird, we moved our cats there too.
