Answer

Use singular if you are referring to one cat:

I loved a cat until I realized it was not clean.

You can also add words like particular for a clear meaning:

I loved one particular cat until I realized it was not clean.

If you are referring to cats in general, use plural form.

I loved cats until I realized they were not clean.
