As K & L said "They can only make you feel bad if YOU let them!" That's very true, but it must be very sad and disappointing for you when you cannot share your pride & joy
with some friends or family members. It's probably best to try
hard to ignore them or let them tell you how to live or care for
the kitties. I did read your other posts(with pics of Lily) and I
think she is beautiful & will make a lovely, contented inside cat.
I share the worry about her being outside now because of the
diseases she could come in contact with while outside. Hope the
time flies till you'll be able to take her home with you & Luna.
