We got a kitten from the HS about 6 months ago. A little Siamese boy. We really wanted his little sister, but they have to be over a pound to go home with "regular" people. An adoption cat person took her 2 minutes after we were told we could not.
Anyway, they nuetered, dewormed, vaccinated and defleed the poor little guy all in one day. He was healthy when we chose him but incredibly sick within 2 days of bringing him home. There is a respitory illness that is running rampent in HS's right now. He was gravely ill for 3 weeks and then got much better. He is seriously the best cat I have ever owned! Such a cuddle bunny. Unfortuntely, he has a cronic(sp) sinus issue due to that illness. We have nicknamed him "Snuffles" because of it. He is still worth it, though. I would reccomend a Siamese. I have had all types and they are truly the best of the bunch. A boy, also. Seem sweeter than girls.
Good luck!
