Just because you care for someone (friend or family), it doesn't follow that their opinion is right.

I lost a friend last year because she decided out of the blue that SHE FELT that my loving partner was not right for me. When asked to make a choice he WON and I learnt the above lesson. Friends can be wrong.

I was told by my cat loving (in the singular) mother that my house would smell bad with three cats. Recently she commented that she was surprised the trays didn't smell (My tip add baking soda sprinkled in the bottom of the trays before adding litter).
Family can be wrong.

We only have one life and who cares if others disaprove. As long as we are not hurting anyone else, we should be free to life life as we choose to.

I don't talk to my work people, friends & family about my cats, they don't understand. I save my cat talk for Stevie and PT people.

Lily belongs with you and Luna. Ignore those who critise.

Personally I don't think friends who tease you about your care of your cat deserve to hear about her.
Post more photos here. Luna is one pretty cat I for one could not read enough about her.
