Some random thoughts about cats after having owned 12 over the past 50 years.
Shedding is a fact of life for almost any cat except the Sphinx. If you don't like fur in your environment, don't get a cat. I currently have two and am cleaning up fur CONSTANTLY. We have both carpet and hardwood floors. It's a lot of work.
Siamese are VERY loud and vocal and in your face. I don't recommend getting one unless you enjoy this. I have had a half-Siamese cat and she was amazingly loud. I loved her to death but could have lived without the noise at times, especially in the middle of the night.
Short hair doesn't mean no shedding. I've had longhaired cats (Birmans) who barely shed and my current cat Sam has shortish hair and sheds all. the. time. I can brush him for 20 minutes and he's still shedding.
Furballs. Need I say more. Not fun. Also a fact of life, even with frequent brushing.
I am not an advocate of outdoor cats. Between predators (yes, even in the suburbs), disease and cars, their lives tend to be short. I have had both and highly recommend keeping them indoors at all times. The last three cats I've owned have lived 17, 20 and 20 years respectively. Yearly vet visits and no outdoors keeps them healthy.
Also not an advocate of de-clawing. It's not necessary.
Vet visits are expensive. If you don't want to take the cat to the vet or pay for it, don't get a cat. They need care just like we do, including dental care. And as they age, it gets more expensive.
Life span: if you're not prepared to take care of the cat for 20 years, don't get one. They can and do live that long. It's a big commitment.
Having said all this, I love my cats, all of them living and dead. I would not have had it any other way. My husband says these two are our last ones, but he's in for a surprise.
