For this reason we walk our cat. With some training (and some - not all - cats) you can even get rid of the leash and let the animal roam whilst maintaining visual contact.
It's very different from walking a dog. Ours usually hides in his favourite spot and just sits there for 20 minutes straight, then takes his usual route, sniffing and rubbing his face on places where apparently other cats have been.
The upside is that you only need to do that once every 2-3 days.
Now that we're on quarantine he's been calling out other cats from the balcony. Fortunately on Monday we'll be allowed outside, so he'll get the chance to catch up with his buddies - or actually - their scents.
