just make sure your house is safe-ie no friends bringing round dogs, or letting screaming curious kids pick them up by their heads ect. Cats are not generally great around children. Make sure they have somewhere to sleep-i do suggest buying a cat bed-or anything that resembles a large pillow-reason being if you dont train a cat to use a cat bed when they are a kitten-they never will, and they will most definately get into the habit of using your bed as theirs-which is fine if you dont mind-mine always used to sleep at the end of mine but i used to resent the cat hairs left afterwards and they are hard to brush off. Cats that go out do also get fleas-as much as you de flea them, and you dont want flea poo/eggs in your bed sheets. In regards to food-i prefer wet food, how would you like to be fed hard biscuits for the rest of your life? plus if they develop any teeth problems which cats often do during adult life they will find eating painful. In any case you should give them kitten food first for a few months as their tummies are still quite sensitive then go onto adult food afterwards. Iv had many cats and kittens over 20 years and my advice has always gone good for me. One thing i definitely reccomend is Pet insurance. Vet bills are prohibitively expensive and the smallest of injections can cost minimum of £40. My cat was very ill before he died and the resulting treatment over 3 days came up to £750. And thats without operating. My other cat had to have her teeth done and that cost almost £100. so consider your finances first before getting a pet, and consider insurance that has no excess either. I have a cat who is almost 17 and she needs looking after alot-dont get a kitten based on playfulness/cuteness ect-kittens turn into cats quickly so be sure you are able to look after it properly-ie feeding it properly and on time, giving it your time-interacting with the cat, (this helps it to become more sociable too) ensuring it is safe-ie ensure it cant get out of your garden if you live next to a motorway, but if you cant help it at least make it wear a reflective collar so cars can see it, microchip it and NUETER IT!, unless you want your cat roaming for miles increasing possibility of it being run over, or spraying the inside of your house, and trust me you dont want it doing that-it smells really really bad and the smell is hard to get rid of-plus its being responsible by neutering to help stop him fathering strays adding to the stray cat populaton. Other than that cats are the best pets and will reward you with love and affection always-be nice to it and it will love you in return. You dont need two cats-one is fine, especially if you are letting it out to entertain itself. I loved playing rough with my kittens and i found they still bit (playfully-but can still be hard!)b as adults so play gently if you dont like that sort of thing. (i do haha)
