i just wanted to know how many times a day we would have to give him food, Could we just refill his bowl when its empty or give him the food at specific time and wait for him to finish then dump what he left behind? Dry food or the canned wet stuff ( What's the difference? ).
Do you know if you will be getting a cat or a kitten? Feeding depends on their age -- kittens are generally free fed (putting food out at all times) while adults should have meals at specific times so they don't over-indulge themselves. Also, most people on this message board feed mostly high-quality wet food (see the Health & Nutrition section for details on types of food) and a little high-quality dry. Other people like me feed mostly dry and some wet (one of mine has a weak stomach for wet and another just won't eat it). Also, keep the cat on the same food that he is eating at the shelter or wherever you are getting him/her from and mix in new food gradually -- the cat will get sick if his food is switched immediately.
Is it okay to keep him in a confined area until i come home from work then let him roam , will keeping his litter box in there teach him to go in it even when he's running around the house?
I would suggest confining the cat to certain area of the house for a little while so he can get comfortable with the smells and sounds of your new home. And the cat should take to the litter box immediately, so you shouldn't have to worry about that -- just make sure he knows where it is! You also can make a room, like your bedroom or a spare room, his home while you're out.
Also we have 3 guinea pigs , i've been reading much about Soft paws , Would these work if he likes to torture them?
Sorry, but I don't know much about soft paws -- if you're worried, just keep the cat away from the guinea pigs if you are concerned. I know there are plenty of people on this board with other pets -- rabbits, hamsters, etc. -- and the cats do fine with the other animals.
Good luck with your new kitty -- post some pics if you can!
