These are the species in the cat family.
When you do an image search, you will inevitably find that many results are not exactly what you are looking for, and some will seem completely unrelated. When you do a Google web search, and choose the “cached” option on a result, it shows you exactly where your search terms appear up on that page – so it’s easy to see why that page was selected as a result for your search. However, sometimes your search terms don’t actually show up on that page, but on related or linked pages.
Here is an example. I searched for “feline species” and one of the top results was the Wikipedia page for Felidae. The word “feline” does not appear in this page (since this is the cached version, it says so in the grey bar at the top). However, some pages that are linked to this one do contain the word “feline” (or that word is used as a search tab as @WillWorkForChocolate mentioned), so this page still turns up as a result of the search for “feline species”.
That’s just how Google works. The same thing occurs with with image results (though you don’t have the option of seeing a cached version). I wouldn’t worry about it too much.
