  The origin of the cold phase in the CGM is a highly debated question. We
investigate the contribution of satellite galaxies to the cold gas budget in
the circumgalactic medium (CGM)of a Milky Way-like host galaxy. We perform
controlled experiments with three different satellite mass distributions and
identify several mechanisms by which satellites can add cold gas to the CGM,
including ram pressure stripping and induced cooling in the mixing layer of the
stripped cold gas. These two mechanisms contribute a comparable amount of cold
gas to the host CGM. We find that the less massive satellites ($\leq 10^9
M_\odot$) not only lose all of their cold gas in a short period ($\sim$ 0.5-1
Gyr), but their stripped cold clouds also mix with the hot CGM gas and get
heated up quickly. However, stellar feedback from these less massive satellites
can hugely alter the fate of their stripped gas. Feedback speeds up the
destruction of the stripped cold clouds from these satellites by making them
more diffuse with more surface area. On the other hand, the more massive
satellites (LMC or SMC-like $\sim 10^{10} M_\odot$) can add cold gas to the
total gas budget of the host CGM for several Gyrs.
