Maybe Grandma is upset by all of the antics during the night with Angel.
Sounds like neither you or Grandma got a good nights sleep.

MOFF, I hope you feel better soon.

I find that my cats have good days and bad. Sometimes Rascal is one huge love bug - like today - and other days he wants nothing to do with me and just wants to sleep.

I hope Grandma settles down for you.
