These guys are the best. I have to admit I don't like taking my pets to the vet but I had to make a trip recently because my pet was starting to concern me. I thought my cat had mange or some type of bug. I went in after they opened, signed in and waited for about 20 minutes. Best wait time experience, similar to a walk in clinic for humans. The vet tech who called me in was friendly and very professional.
After my feline companion had his stats taken the vet tech left and came back a few minutes later with the vet himself. He came in looked at my cat (including his underbelly, he's so fat!) and then checked his ears and the scabbish looking spots where my cat had been scratching. He was able to come to a quick diagnosis and offered me two solutions. Apparently my cat has an allergy to something in the apartment we live in.
Needless to say I was totally at ease with this vet visit and would highly recommend them to anyone else.
