I'm so sorry for your loss, it's never easy and everyone deals with it differently. There's no right or wrong way to say goodbye just whatever feels right to you.
Hello and welcome, she is adorable! I have a mini lion lop so i love the breed of the lionheads :) I got Poppy spayed when she was just over a year old, the vet advised anytime after 6 months and the op was fairly straight forward and she recovered really well from it.
Looking forward to...
I would agree to get her seen to by a vet in case, it does sound like she hasn't took though but if it was me i would want to get her checked just to err on the side of caution
i would take her for her check sooner rather than later just to check the red stains and also the fact that she isn't eating hay it would be worth getting the vet to look at her teeth and make sure they aren't getting overgrown
