She has lived in Corvallis since 1984, on the same piece of property where the clinic is now located.

Our Feline Staff


Vladimir the Cat, employee of All Creatures Great and Small Veterinary ClinicVladimir is our “greeter!” Vladimir was a stray kitty that needed a home. I took him in when I opened the equine boarding facility in 2006. He was going to be my barn kitty and catch mice. However he really never wanted to leave the tack room and I never did see him with a mouse. When the vet clinic was being built, he decided to leave the barn and claim the reception desk as his own, even before the walls were finished! I don’t think he has ever left his spot atop our reception desk, thus fullfilling his job as our greeter! He always makes himself available to pet, unless his hunger pains overcome him in which case he has clocked out and is waiting at his food bowl.

Sunshine a.k.a. “Sunny”

Sunshine the Cat, employee of All Creatures Great and Small Veterinary Clinic(seen here, multitasking, keeping an eye on Vladi and the front counter at the same time…) Sunshine and Autumn are the “chief mousers”. You will see Sunshine, the big orange kitty, in and out of the clinic all day, letting us know just how hard he has been working in the fields. Occasionally he will come in and take a nap…such hard work out there catching all the field mice!!!! Both Sunshine and Autumn arrived on the property 1 day after Vlaidmir (I thought he needed some company). Both were only 4 months old and at first Vladimir hated them! But after only 1 week, he was actually letting them nurse on him in order to keep them out of trouble!


Autumn the Cat, employee of All Creatures Great and Small Veterinary ClinicAutumn is the big calico who has taken on the job that Vladimir left when he started work at the clinic. She keeps the hay and tack room clear of mice and catches them before they run under the stalls and scare the horses!


Leon the Cat, employee of All Creatures Great and Small Veterinary ClinicLeon is the “bug getter”. Any bug that makes its way under the doors are arrested in their tracks. He also loves a shoulder, so if you are having a bad day, he will happily crawl on your shoulder and rub his face on your neck. He came into our clinic 2 years ago as a tiny kitten. He had a rough start to life with his eyes stuck shut. For the first 2 months of his life he was blind, but after several surgeries, he is able to see fine, but his tear ducts don’t work, so he has chronic discharge around his eyes and sneezes alot!! The other kitties accepted him, so he was eventually given a permanent home at the clinic.
