The gamma-ray pulsar in the CTA1 supernova remnant was the first to be discovered in a blind search with the Fermi LAT. With a surface magnetic field strength of 1.1x1013 Gauss, this pulsar has the highest surface magnetic field strength among the 46 gamma-ray pulsars detected by Fermi in the first six months of the mission (Abdo et al. 2009). In May 2009 this pulsar had a glitch, Df/f=5x10-7. This is one of a few glitches detected to date in Fermi gamma-ray pulsars. We will present results from the first 15 months of the Fermi mission. Detailed studies of the energetics and variability studies of this source, especially around the time of the glitch, will be presented. The surrounding region contains both a PWN and SNR, which provide constraints on the age and energetic budget complementary to those obtained from period derivatives.
