Transition from Romaji

I just recently started learning Japanese. In the beginning I used flash cards with romaji just to get me started and then planned to transition to Kana.
I have basically memorised Kana now however I still can’t read it properly without reading it as individual characters. For example cat, I would read like this c-a-t. I have been trying for a few weeks but it’s not happening.
Any tips? Or maybe I am not cut out for it
