Whether it is a basket of reeds, made of metal or wool, does not matter much. The round wicker basket is a frequently used item in the interior. Currently you can find baskets from mini to XXL in all kinds of styles. With this interpretation you can really go crazy! Because whether it is an olive tree or a small cactus, there is a nice basket for every plant. If your metal basket is too big, a good piece of natural linen will ensure a nice transition to the plant.
And at the same time it ensures that you do not see the pot itself. The authentic way done, is certainly not for every interior. But you can also hang the baskets upside down on hooks and give them a more modern look.
Nothing stops you from using them as a storage basket when you hang them up. That, of course, depends entirely on your choice of basket. You want your animal to be in its best place and also a bit of styling justified. A basket can then be a perfect option. For a cat this is a little easier to use as for a dog seems to me (depending on the size of course).
