Kate - I must say I am so sorry that doubts have been fostered regarding your new acquisitions.
I'm sure you will make a good home for your pets, and I am pleased that your vet's report is good.
We had a crate for Prince when he was younger, and he was quite happy with it. If he seemed nervous
about anything we used to drape an old blanket over it to make a den or 'safe haven' for him and he loved it.
(Hugs for you and for Oscar)
