DEAR PET TALK: I have the time and space to foster a cat. Can you help me do that? -Hopeful. DEAR HOPEFUL: God bless you! Foster families are definitely needed for cats – also dogs. Fortunately, there are a variety of rescue organizations in North and Central Massachusetts who help get cats off the streets, or who take cats that need to be rehomed. It’s hard for a cat who has had a home to adjust to a shelter.
