Can I keep a cactus indoors?
user
Sure, cactuses and other house plants are OK for indoors, but I should point out that a lot of species will need to be grown in larger pots to accommodate their size over time.  If you just bought it today, you might be able to keep it in the pot for a couple of years, but by then you might want to consider getting a bigger one.

Okay so when they get bigger I need to change th pot?
user
Yeah, it’ll keep growing bigger and bigger, and the roots will start to go everywhere inside of the pot.  It might not look too bad for a couple of years, but eventually they’ll fill the pot and spill out.  Maybe for your home cactuses you could ask your friend if they have any for sale?

Hmm, I can just buy them online
