The Clinic Has Been Solving Cat Behavior Issues For Texas Felines in Austin, Dallas, Houston and Beyond Since 1999

Many of our clients schedule either a phone or video consultation (especially if you’re located out of the United States), but depending on your location in Texas, in-home consultations are also possible.  Dr. Shultz conducts vet-to-vet video consultations.  Prior to the consultation, we ask that you complete the Feline Behavior History form so that the clinic can evaluate your cat’s behavior and begin preparing the behavior plan.  Our clinic efficacy guarantee:  If after reviewing your completed feline behavior forms the clinic determines that a consultation would not be appropriate or helpful for your cat’s behavior issue(s), they will perform a consultation at no charge to help guide you in what the best next steps would be for your cat.
