Hi Emily, @Matthew285 is right, some potential guests just won't read everything they should!
With something as important as pets on the property, it is a pity that Airbnb makes guests actually search out this information! What guests DO prominently see is 'Not suitable for Pets'! and it is not until they open the house rules section that you make specific mention of your cats. Also I did not see a photo of cats in your 12 listing photos, so I can understand how guests can pass over this information when viewing your listing. When they get to the 'Things to acknowledge' section, they just go....yeah, yeah and click whatever to get on with booking it!
It may be better to kick off your listing description with...."Come and stay in the Spanish Block with Emily and James and out two adorable cats. I can assure you we are all great hosts"!
They won't miss that Emily because it does bring an element of humour into the description and it is the first thing they will read under your profile picture.
I have found that humour is a great 'icebreaker' and you may find this will limit much of that 'solid third' of people who cannot comprehend what is being described.
Give it a go Em!
Cheers.....Rob
