Is it to late to save my indoor palm tree?

i have an indoor palm tree that seems to be dead. the the way it happened is that my cat started to use the dirt in the pot as a litter box. the plant started to stink so we put it out in our garage until we could re-pot it. One day my son comes home and leaves the garage door open making it susceptible to the freezing temperatures outside. the plant is now wilted and has an extremely pale complexion on the stem of the tree. i was wondering if i could just cut the plant off at the base and hope it will grow back or is it too late?
