how to carry them around
For daily outings in the company of your cat, different types of bags and shoulder straps are available, also equipped with carabiners to secure the animal's harness, so that it does not escape.
On the other hand, if you are used to it from an early age, you can take it on a leash, obviously you shouldn't expect it to obey and follow its owner like a dog.
It is important to always keep your pet under control, as otherwise it could be dangerous.
