This depends on where you live. Cacti are native to many places.
inside your house or outside o_o and no it should leave if it gets hungry or something or it may just die but if its not hurt or anything it should be fine to leave it

I don't know if you are looking for any specific person, but if your question is why should you leave the shower curtain on the inside of the tub, the answer is simple. If you leave the shower curtain on the outside of the tub and take a shower, the water that runs down the curtain will be on the floor outside of the tub and you will have a mess to clean up. But if the curtain is on the inside of the tub, the water just runs out of the tub and thee is no mess to clean up. Conrad Hilton said it.
park outside a the bank, put a skunk inside it and leave
In general, you should avoid putting plumbing on the outside wall if you live in a freezing climate. If you MUST use the outside wall, insulate heavily to the outside and do not insulate between the pipe and the heated area of the house and leave a space for heated inside air to ciculate around the pipes.
leave, i leave it outside
you can leave your cow outside but you should plant grass that is ready to harvest but don't let it out on rainy days
It would be advised if you do not want to get cold.
Leave it alone. If it is in the house, slide it on a paper and then take it outside.
No, If yours is you should take it to a vet. but dont leave it outside.
you should mabey cover it with tree covers I think
well if was very hot outside and you left it outside then put alot of water and some food out there and have some shade for the dog. If its a puppy i would not (under 3 months). inside is good too but you might have to clean up some mess but u could not hold it that long ether
