Our two rescue cats, Thomas (semi long haired) and Alfie (grey). Both three years old, were brought up together but are not related. We have lived together for almost seven months now and they are both little sweethearts with big personalities.
On what to feed your cats and reading some inaccuracies on this thread, I would like to share a few tips. We fed our previous cat Georges, who died at the good age of 16, dry food, Hills or Royal canin, most of his life. He had mild asthma for years, ie he coughed a few times a day. We changed to wet food the last few months of his life and the coughing stopped. So possibly an allergy to the ingredient: grain and a lot of it. Dry food is highly calorific so a wet diet is preferred and if you cannot do otherwise then check carefully and do not think that because it is sold by your vet that it is the best (we did!). Wet food can be confusing too but check ingredients and contact the manufacturer for the calorie count so you get a better idea than the 4 pouches a day/1 tin a day. You want high meat content and little filler and no sugar. You can buy wet food elsewhere than the supermarket. Check zooplus and happykitty websites for example. Raw meat is great too but you need to know what you are doing. I give the boys raw meat regularly which they absolutely adore. Its great for their teeth and jaw muscles.
Of course you have to do what is convenient and buy what you can afford but it is really worth doing a little research for yourself to have a better understanding. I think a good variety of food is probably the best rather than the same food every day with high quality meat. Tuna should apparently not be given to cats. Our boys are food monsters so it is really easy to feed them as they eat in the same way. I struggled figuring out how much to feed them but once I got the calorie count it became a bit easier.
As to adopting a cat, don't go for a kitten if you work full time. Kittens need your full attention. If you want a breed, check breeds websites. You'd be surprised how many bengals, for examples, are to be re homed.
