Unknown Catt. that won't bloom

[Rhonda Svoboda]

I've had a Catt. for years and it just won't bloom. I repotted it this week and holy cow!! way overgrown. I grow it in full sun in the summer and under grow lights in the cold months so it gets plenty of sun.
I fertilize regularly and give the same conditions as my other high light orchids but it refuses to bloom- any ideas?
It also produced two baby's that I potted seperatly.
Thanks
