Quotewithout being spayed she can get pregnant up to 5 times each year
That may be just based on calculations since they've a short gestation period. In reality I don't know any cats getting pregnant 5 times in a year. Anyway that's how God designed their system (remember, God has also designed animal species which can get pregnant only once in a year and bird species which lays only one egg per year!).
The cats which I know used to get pregnant twice or upto thrice per year if I'm not mistaken, and sometimes they are not, for long months or may be for a year.
Animals/birds die for various reasons, for example when they die because of extreme weather conditions - may be one of the way God giving humans warnings that they are destroying the planet (climate change).
One reason for the increasing number of stray cats, dogs, rodents etc & their reproduction is Food waste (food that is fit for consumption but discarded at the retail or consumption phases) by irresponsible humans, they waste lots of food, also not disposing it properly. So maybe God warn them and punishing them with such disturbances.
Food waste is also a major source of the greenhouse gas methane.
Of course neutering/spaying is not forbidden in the Qur'an, but there is no any examples/hints for any such mutilating acts in any case. When God says He provides for them (11:6, 15:20 etc), neutering/spaying animals by fearing that they die without getting food seems to me an atheist/disbeliever way of thinking? (as if there's no one to provide for them).
Also, many of you might be knowing that how enjoyably the mother cats used to play with their kittens, even with grown kittens. But by fixing the cat, you're forcefully taking that God given enjoyments from them, permanently!! (I suppose fixing is not reversible).
And like any other species, cats are also part of food chain, some times God creates kittens as food for some other species.
