I pay with my credit card ,not sure if they allow accounts. Although our Fosterers can have anything they want to make their life easier and the life of the cats as comfy as possible, they are not allowed to order and pay for things themselves. I and the treasures like to keep tabs on purchases. Although I am sure if we asked they would not mind using their cards as they know they would be reimbursed immediately. The Fosterers however do order their own litter £150 at a time.
We use Vircon (from the vets) for cleaning out or Vetaclean from Animalcare via IdENTICHIP rep.
We get the traps from MDC. We have 12, the last two we purchased were the collapsable ones but we have found them as much use as a chocolate teapot when they are used for kittens, as they can get out.
