Absolutely wonderful. My cats are super sensitive and took right to them. I was amazed. Cannot praise them enough for improving my kitties' quality of life. Even if you are worried they all have a just positive attitude. Excellent technique in calming old/scared pets ( and owners)- GREAT attitude. Kindness with real knowledge. Also affordable - fair pricing. They are the whole package as they say. My pets and I cannot praise you enough. You all are the best - Tang sends a special purr to Dr. Jones!
