r10 has some good sense and humour to share.
r27 thinks he knows more than a cat, or that you can control the outcome based on breed or peoples opinions and you will have minimal success with that.
Ok, now for my opinions.
Get a cat from a shelter if possible. If you are up to kitten lunatics, it is a lot of crazy fun and scratches and interrupted sleep. They will be no more bonded to you than if you choose a cat that is one or two or three years old.
Always get them fixed. Always.
I like female cats better, they are often a little less sucky but also are less prone to urinary infections than males.
I had an object of art cat, Abyssinian and she was a lovely sweet thing with me, very shy and admired by others. My present cat is just a cute tabby that was 2 years old when I got her and is so strong willed, smart and playful. She is very social and completely disobedient to most anything I say but really doesn't do much wrong anyway.
GO by instinct when choosing a cat. If they are 12 weeks old and look like Egyptian sculpture they may be chinless and pudgy by one. Look for bright eyes, responsiveness, alligned strong back legs and radar ears. See if they respond to your voice and fingers.
A cat personality is gonna be fun, and maybe hard to understand, but they are very much smarter than people think, though it is not necessarily about playing fetch. Winks, word associations, hiding things, running and giving them the illusion they are being hunted or hunting is fun for all young healthy kit cats. Cats are a freakin joy once you understand that they are fully willing to play and can learn a lot, but it is not about obedience training or shaking a paw. They may like to please, but it has never been proven. They like to interact.
Two cats are better than one if you want two cats. One cat is just fine with one owner if you plan to be a good roommate for them. They will see you as the guy they live with who brings food, and they will be as great company as you are. If you are not going to be around much or just think of a cat as low maintenance fluffy, then best to get two or none.
Sound is a cats best sense and therefor the best way to train or discipline. Fast hard claps with a firm "NO" is better than any water bottle confusion or attempting to move them around. Listen to me. Two hard claps of your hand and a masculine "NO", will get most cats down from the kitchen counter or out of the wet tub.
Soft sexy sweet talking is very effective too. Not kidding and not as weird as it sounds. I like dogs, but dogs are like children, you have to repeat and use commands and rewards - cats are more like aloof boys you want to long term seduce. Provide food and a bed, don't make too big a deal of any of it, but talk sweet to them and sometimes dance and show off to them. Be Patient. They come back.
Scratching things is a problem you will get or not, and then you will have to figure it out. It is instinctive behavior, that can be neurotic, but if you are frightened by primitive instincts including the love of the kill, you are going to have a hard time understanding a lot of what a cat does.
Never hit an animal of course, but if you have to be firm, shake the scruff of the neck, or pick the cat up that way to get it out of harm's way.
NEVER hit a cat in the face. Butt your head up against theirs for affection, like their mother would do. Most cats like it firm and steady, full body strokes, some tail pulling and ear scratching. Be respectful of their face. They will never bite or scratch yours. Funny.
Kidney disease kills most cats, so they need high quality protein and mostly dry food. Water, some brushing. Cheap treats to run for, and some nip if you like to get a bit nipped yourself.
I sound like the crazy cat lady with 26 cats, but really I responded because our cat is 15, recently pretty ill and I just think she is swell and I am feeling a bit worried.
(Name a cat with a hard consonant as the first letter of it's name. Not Cecilia, but Delta. Not Oona, but Tuna. Not Allie but Cat Deely. Not Umberto but Bob)
