Catts grow more slowly in the winter, but they do continue to grow, so I fertilize with one-half a teaspoon to a gallon of water. However, by the end of this month with all the good light we're now getting, I'm going to increase that to a whole teaspoon to a gallon of water. Every fourth watering is with plain water.

You may or may not have two of the same catts. A unifoliate can often have a few pseudobulbs that have two leaves instead of one, but rarely does the whole unifoliate behave like a bifoliate and have two leaves on every pseudobulb. I may be wrong about this.

As Jerry says, repotting a cattleya at the wrong time can set it back for months. If you can wait a few more weeks as the light gets stronger you'll have a better chance for a happier plant. Catts like as much sun as you can give them, and they like to be wet and then dry out before being watered again.

Some catts develop sheaths, some just develop buds at the leaf axils. Sometimes the sheaths can sit there for months, dry out and look half dead, but when things are just right, buds develop in those sheaths and they bloom. Some catts only bloom once a year, others bloom on every new pseudobulb. Perhaps if you told us the name of your catts someone will be able to tell you more about it.
