My Cat sleeps all day and so deeply nothing I do wakes him except if I shake him...I don't know if this is really normal or not...I am getting worried..he seems to be doing this more often. I can't take him to the vet for a few months (saving money to fix him) and I just need to know if it's normal for him to sleep so much and be so hard to wake up..none of my other cats are this way.....
