Feeling sad today..

Today is a down day for me. My mom and I are 99% sure my 15 year old cat stub's has mouth cancer. His left cheek has been swollen for well over 2 weeks and the last few days he's been bleeding out his mouth. We can't take him to a vet because he gets way to stressed out in a vehicle and would probably die on the way there and at his age they would probably just tell us to put him down but aside from the swelling and bleeding he's eating fine and being his old talkative self. It doesn't seem to bother him but if it Start's to we have pain meds that we can give him. We are going to try our best to make him as comfortable as possible and even though its hard to say we hope he just passes away in his sleep without having to be like this to long. Just needed to vent because its like 10x harder to deal with when your pregnant and your emotions just wanna take over.
