I know you said you were dropping off Leo last night for his neutering. Did you get any sleep 'all by yourself' last night? I can remember how empty the bed felt when Gracie Ruth had to spend the night after her spaying.
Even with DH & Boo in the bed it seemded so empty without her little body sprawled across my neck.
I'll be saying prayers that everything goes smoothly today. Please let us know when you hear something.
