I don't know what's happening with Spike.
Suddenly, she's spry again. Jumping into our bed at night to purr and to let us "pat" her - that means I stick out my finger and she rubs her face against it.
For a while, she was sleeping all day and all night and limping around. We were pretty sure these were her last days.
TJ took to calling her "The Cat That is Going to Die Pretty Soon" (as opposed to other two - "The Cat That Bites" and "The Cat That Has Front Claws" - actually I am pretty sure he knows Taylor's name, just gets Spike and Toby confused.).
Even her bumps are going down. Except for a few of them. In particular, one on her mouth that makes her look like she's constantly sticking her tongue out.
Dustmop is one strong kitty.
