Catz, aswell as CP, the other smaller rescues in your area would probably like another fosterer.
With CP after you have fostered in your home for 6 months, they will consider offering you a pen in the garden.
Fostering is a great experience, sometimes difficult but seeing them go off to their new homes all healthy and happy outweighs that by far
Do you want to foster mums & kittens or oldies or ferals? Or a bit of everything!
