I would disagree that cats are solitary animals. Some are, mainly those brought up alone or with one other cat. Those used to other cats thrive with company. As I type, four cats are bouncing around a tree outside like squirrels together having the best time, while the poultry marches around underneath getting frustrated because they can't see what's happening and they are VERY nosey.
Per square foot I am certain my cat density is way lower than the average street. About 1.2 cats per room and unlimited space outside where no cats other than these roam. We're miles from anywhere with fields and woodland and swampy areas right on our doorstep.
However, with the right combination of cats, they could easily manage in a smaller space.
The house, as I said, is spotless. Roombas and scoobas run constantly and all the floors are wooden or stone. I can wear black clothes safely (as long as I don't cuddle the deaf white cat) as the house is kept very hair free. Thanks irobot.
As thecatneuterer does, we have a two flap system so feet are cleaned on the way through.
All pets are free fed with unlimited food of the higher of the middle range quality so no-one is ever hungry. A LOT of bickering in pets is caused by anticipation of food. Waiting is very stressful. Our pets never have to wait as the food is always available. No-one is fat. They're used to free feeding and eat what they need.
The ill and geriatric get the absolute top end food.
We have a couple of trays. Only the very young and very old use them. The rest go out into the woodlands.
The cats don't bother with birds much as they live with free range poultry. They did catch rabbits, but I don't think any are left in the immediate area so none the last couple of years though the fields further away abound with rabbits. They are crap at catching mice too. We have a lot of hares around us which I suspect is due to the lack of rabbits. They have cleared out the local rats which I appreciate.
Two of our cats are prickly if other cats invade their space. We are very mindful of that and intuitively move them if they find themselves somewhere where the young cats are throwing themselves about. It's all about knowing each personality very very well.
Most of my pets are rescues. I'm no martyr or special person for taking these pets. I have the pets because I get so much out of them. They are an absolute delight, and make me smile throughout each day (with the odd bit of cursing when someone vomits in a shoe or something equally ridiculous)
I do understand that people with a lot of cats are grouped into a stereotype. With some reason. But not everyone fits into that stereotype. Ask questions fully before leaping to conclusions.
Our pets are very expensive. But probably cheaper than 20 cigarettes each and a bottle of wine a day.
And breathe! I only came on here looking for other people with multi pet households to compare notes with!
