I thought about the word ‘cat’ and thought about the individual letters but didn't consciously count them before I forced my attention away. On the other hand, I rarely consciously count numbers that low, so arguably I was thinking of the number as soon as I thought about the triplet of letters. I'm confident that I didn't subvocalise the word ‘three’ (or otherwise imagine any symbolic representation of the number) until I began reading your last paragraph and your quotation of that word came into my consciousness.
