Alas, rather than a spike (also called "stem" or "stalk"), what you see is a new pseudobulb growing. But don't be too disappointed. New pseudobulbs are where you will ultimately get those flowers from. Once a pseudobulb blooms, it will not do so again, so new growth is what you want to see. Many cattelya are coming out of their dormant period, and thus are putting out new growth.
I would need to know your growing conditions, including but not limited to: growing medium, pot type/size, and light, to help you with growing tips.
Cattleya are what I feel in love with almost four decades ago, and though I now grow other genera, cattleya are by far the most plants I have (several hundred).
