Scientist are getting better at understanding and manipulating DNA. that gives hope that eventually scientists might be able to genetically engineer an allergy-free cat for people who like cats but can’t own one.

People with cat allergies react to a single protein known as Fel d 1, which probably has a role in keeping cats’ skin healthy and may also interact with their hormonal systems. Male cats make the most Fel d 1; neutered toms make slightly less, and female cats less than that.

Despite knowing this, scientists aren’t likely to make an allergy-free cat any time soon. Until then, you’ll have to content yourself with cat videos on the Internet.
