That sucks, and as rough as it will be to hear, you probably need to prepare yourself...
Last year my cat, who was about 13 years old, started acting similar to yours, but a little more dramatic. I woke up on the morning of my birthday no
less, to him cowering under a shelf, his eye were dilated and he was growling for no reason. I've lived alone for 4 years, with no other animals.
He'd always been a cool, relaxed cat (except for when he'd take a dump, afterwards he'd always sprint across the walls like his tail was on fire,
lol). I tried a bunch of stuff to calm him down, see if it'd pass, but it kept getting worse. He'd freakout for no reason and go hide somewhere,
then he started limping, he'd limp over exhausted after getting a break from whatever the hell was bothering him, and just start meowing real weak.
I took him to a vet a couple days later, they ran tests, didn't find anything, brought him home and he just kept goin down hill, I took him back and
they kept him overnight, ran some xrays and did an ultra sound, found nothing, but concluded that all his symptoms pointed towards a tumor near or on
his spine. I had to put him to sleep the next day.
Still not really over it, I had that big fat garfield for over a decade, he'd moved with me about a dozen times across 3 states. When times were bad,
and life was hard, I always had my buddy. The ultimate lap cat, always clung to me like velcro. Every night when I went to sleep, he'd crawl up in
my arm pit, lay his head on my shoulder and throw a paw across my chest. It was like losing a little brother.
Just remember they were here for a reason. Our pets are natures way of reaching into our homes, lives and family and loving us. Loving us
deliberately, with a mutual unspoken purpose.
