Whether you alias your plural tables to singular nouns would probably be one of the very last things I would check out if I would need to assess your code.
And you should not but I think it is still useful. You will probably not even become consciously aware of the difference but Cat.Name will be ever so slightly easier to read than Cats.Name and maybe that difference in cognitive load is what makes you spot some issue that you would have missed if your brain got repeatedly slightly tripped up by incorrect grammatical numbers.
