Eeek! So excited about collecting my little 2yo tortie tomorrow.
I have bought:
Cat carrier with towel inside
Food mat, 2 x bowls and supply of food (same that she's on at the sanctuary)
Dreamies
Litter tray and big bag of litter
Litter scoop and liners
Scratching post
Couple of catnip toys
Couple of throws that I'm hoping she'll want to sleep on 
Will be purchasing worming/flea treatment in few days, she'll come from the sanctuary freshly de-flead and de-wormed.
Have I forgotten anything?
