When I was still trying to be Catholic, I was convinced that a place without animals would be no kind of heaven for me, and I wouldn’t want to go. Still, letting in pets, as has been mentioned above, lets in the camel’s nose (ie let in the nose and soon the whole camel follows, AKA slippery slope), where do you draw the line? Do those who admire butterflies get butterflies in? How about someone who found leeches beautiful in life, does this open up heaven for leeches? I suppose a zoophile Christian will just say something non sequitur like, “God can accomplish anything. those who love their pets get to have them in heaven.” If it were me, I’d want the whole schlemiel, all plants, all animals, fungi, algae, bacteria, etc; as well as rain, snow sunshine, breezes, thunder and lightening. In which case, I might as well stay put right here.
Except eventually you’ll die and then you’ll still have to decide who gets to come with you to heaven (if those are now the rules God plays by.)
It’s all so convoluted and ridiculous!
