I have two 8 week old goslings here kept in a pen in the house at the minute, i have an out door enclosure built for them but its open so next doors cat could get in with ease, i would be really grateful if anyone knows at what age they will be able to defend themselves against her. She is a brilliant hunter i always see her with birds and mice and i really dont want to put them out til im absolutly sure they wont get hurt.
