Wow… I agree, she shouldn’t own a pet – period.
Since she is unwilling to put some thought into it, I’d get a pen and paper, and draw columns for pros and cons.
Pros – She will stop supporting the killing machines that she says she doesn’t like. By not spaying, she is allowing more kittens to be born than can be cared for, and is therefore effectively handling them over to be killed. Very shameful.
– She will be increasing the health and quality of her cat’s life. Mother “nature” is rough. Animals that reproduce as often as that – have shorter lifespans because pregnancy is hard on the body. Just look at quail – those that don’t lay, live 5 years. Those that do, live around 3 years.
– Less stress on her, for having to find good homes for the kittens. Not just crappy homes, but good homes.
– Less guilt for her conscience by allowing kittens to be born and cared for by owners that can’t do it properly. If an animal cannot be taken to the vet when it needs care – it will suffer. She is contributing to that. Shameful.
– She has allowed the cat to experience mother nature, as the cat has had a litter. It is time now to allow the cat to have a healthy life, and to stop supporting the “killing machines”. (I did the same with my rabbits, I let them have 3 litters each, then I spayed/neutered them. I let them have their mother nature experience, and then I took care of their health and future).
Cons – None. And it’s free.
As for the free roaming – totally and completely irresponsible. I used to let my cat run around, because she always came back. Until I realized how many dead cats I was seeing that had been hit by cars. Never again – I don’t let her out of my property. Cats might be quick – but so are cars, and their headlights are blinding. Tell her she is putting her cat’s life at risk.
