I remove it but it just keeps coming back and it’s growing every day.
I hope it’s not a teratoma.
Ack! It’s alive!!!
I like the looks of it. Maybe you should consider it a unique accessory.
A growth like that needs a name.
Teri-Tom?
I was considering cutting a slit on a shirt and doing a little movie of him bursting out of my chest like the alien.
You’re probably catastrophizing, and I think you’ve miscategorized it. I think you should gather it all up - the whole kit & caboodle - and go down to the lab and see if you can get a CAT scan. (Maybe the black lab.) 
PS - on your way, don’t litter. 
Careful, a video like that could shock somebody
into catalepsy.
Do you have a ‘Catscratch fever’ with your condition?
That is a somewhat unsettling clip.
Yep, it’s malignant!
This is just the catalyst I need to take better care of my health.
Does it drag you into the litter box?
Oh Og! WHY did I google teratoma?
Nice cat
You paw thing. You’re not kitten, that’s a heckuva growrth. But I’m sure the doctor will cat it right off, they just love to play with their lasers. I hope you’re feline supurrb again real soon.
I thought you weren’t going to let not-your-kitten in the house? 
He’s adorable!
A Teratoma is a germ cell tumor and it may be present as a painful lump. I hope what you have is not similar to what I heard. Just have it diagnosed by your doctor to lessen your worries.
