We had our Siamese, Blue, for 9 years; he had somewhat poor health from the start, and we lost him last June, he never seemed to fully recover from his dental the previous Oct or Nov (vet cleaned his teeth and had to remove 3 rotten teeth). He was just never the same after his dental.
Anyway, we thought 4 house cats were enough, so we weren't looking to add a cat, but there was a litter of barn kittens last summer and one was Siamese (other two black; mom is Siamese). Come fall and cooler weather, Shayne was like "bring him in at night", that lasted all of about 4 nights, until he was in 24/7 and named B2, as he was Blue Too. He came in the house the first week of November at 24 oz, he is now about 8#.
[These cats that I call Siamese, I don't know if they have true Siamese in them, but they are all pointed. Most are just standard brownish points, but there is one flame point (I think that is right, he's dilute red), at least one lynx point (I think maybe two actually, second is harder to tell as he has white markings too) and one is grey point.]
