i bought this hairy wee barrel cactus out of poundies do you know what species it might be? i don't want it to die lol tysm!!!!!

Unfortunately, we can't help with this one! There are hundreds of species of cacti, many globular like this one, and probably thousands of cultivars. A lot of plants, cacti included, cannot be successfully identified without a flower. One of us has an Opuntia and an Epiphyllum (which this is clearly not - we can rule those out at least!) that require a little more water than usual when actively growing, but care for different cacti may differ. Generally, you would want to let the soil dry out completely, then give it a deep water, while not allowing any water to collect below the pot. Make sure the soil is well-draining. That advice is no more helpful than what a quick Google search could offer, though!
