Count your eleven years as a blessing. From the sounds of it, this is hitting you hard. Be glad you have had the great time you have had. Most pets aren't with us our entire lives but we are their entire lives. Sounds like you have had a wonderful experience and I would encourage you to continue to show the love that you have. My lady friend I sit next to in church has stage four lung cancer and there are no markers for environmental or genetic. I'm going to lose her soon, but I'm not throwing the baby out with the bath water. Live in the present and make time count with people and pets alike.Our big brown Main Coon likely has injection-site sarcoma (Cancer). It is typically caused by the reaction to Rabies and FIV vaccinations. The probability of having this happen is 1/10,000-30,000. He's currently fine and the mass isn't very large but it's basically a death sentence even with surgery and radiation/chemo. I'm talking 2 yrs max. My wife is taking it hard and it's slowing hitting me. The only good thing is that he's 11yrs old rather than say 7yrs.
Ugh.
Rent or Buy it, you learn how special our pets can be from these two movies.
