i dont see the point in people having loads of cats, dogs, or any other animal really
they need feeding (unless they kill their own food, but then what are they killing) cleaning up after and making sure theyre ok
ive got a few plants, and thats as far as ill go, but the kids have birds, a dog, spiders, hamsters and allsorts, and if a neighbours pet killed one of my kids pets, then gave me the 'its nature' speech, id have no problems in speeding up natures way of making sure that everything dies in the end
even though your little girl is upset, its also a very valuable life lesson, nothing lasts forever, things you love will die and be lost, wether its a small pet to a neighbours cat, or a loved one to disease, injury or old age, in a way its preparing her for the inevitable and when a loved relative passes you can now ease the pain by saying theyve gone to look after the guinea pig
