Hi guys! My name is Zelda. I'm the smallest member of the HVHC team. Sadly, something happened to my mom before I was even weaned, so I had to learn to survive on my own until Dr. Amy took me in! I'm now working on growing big and strong, and learning how to be a clinic cat. You will probably start seeing me out and about, and playing with my big brothers Dante, and Cab!


Hi guys! My name is Dante. You will likely see me causing mischief around the clinic. If I'm not out running around, I'm probably on my mom (Dr. Amy's) lap! Daisy, Cab and I all have to wear pretty nail caps so we can't scratch things we shouldn't, but I'm very friendly and would love it if you stopped to pet me! Update: I now live with my brother Cab at Dr. Don and Dr. Amy's house!


Hello there! My name is Cab, short for Cabernet. I can be found causing trouble with my brother, Dante. I don't enjoy cuddles as much as he does, but will allow you to pet me! I have learned from Daisy how to scratch things I shouldn't, so my nails may also have colored caps on them.. how annoying! Update: I now live with my brother Dante at Dr. Don and Dr. Amy's house!


Hello, my name is Taffy. I am the oldest of the office assistants and can usually be found sleeping under a desk. When I do come out and about I don't hesitate to make it known when I want attention! Please don't ignore me.. I only meow louder so that I can be sure you heard!


My name is Daisy, but I prefer to be referred to as the queen of the office! I do enjoy being loved on, but only on my terms. You may see me with colored toenails - this is because I can be naughty and scratch things I shouldn't, so the humans here put these pesky nail caps on. 


Hello everybody! My name is Merlin, and I am the newest member of the Heartland team. I may be the friendliest kitty here and absolutely love ALL of the attention! I enjoy spending my days wandering around finding anyone who will pet me, including clients who are here for appointments. Be careful, I'm sneaky and will dart outside if you don't watch me closely!
