@FrostD...good memory!! Wish I had better news though. I don't know any vets taking new patients, either. For our regular vet, I go to North Seattle Vet Clinic up in Northgate (11032 Eighth Ave NE, Seattle, WA 98125) and I really like them but last I heard they weren't taking new patients. Definitely worth talking to them and explaining your situation, they're really nice and may make an exception.
For the complicated diabetes stuff, I work with
Veterinary Specialty Center of Seattle which is an ER in Lynnwood (Dr Polly Peterson) recommended to me by our regular vet. Minnie has had a a few DKAs and hospital visits so I wanted a internal medicine specialist (was working with Blue Pearl after first 3 DKAs and not especially happy with them, and then they shut down in the summer anyway!). I'm pleased with VSC. It was a long wait time for the first appointment though I did get a cancellation. Think I waited about 2 months. They're right off the I5 exit and close to 405.
The other place my own vet suggested for an internist was
Animal Medical Center in Shoreline. The only reason I ended up at VSC is because they had an appointment first.
And on a side note, I have been looking for someone to have on reserve for cat care when (ha! more like if) I travel. I was happy to get one of our vet techs to cat sit one weekend, but if you're interested in someone to exchange duties with let me know! I'm located close to the Space Needle. Nothing urgent.
Good luck!!
PS what a beautiful kitty you have!!
