I thought about telling you what I think since I read your post and I have animal friends aswell, it's not any deep dymentional perspective, it's simply my perspective from being a normal human being.
If I was in your situation, I would look at things deeply, honestly, specially in the moments that are important for me because I get into emotions, those are the moments that most matter. I have a beautiful dog, when she dies that she will die soon because of heart problems, I will be so thankfull, so thankfull that this animal was with me all these time, sharing her way of being, bringing to myself new ways to discover myself. She will always, aaaalways be with me in my heart, and not a single day I will say "you are gone so thereforce things are bad and you are not with me", everytime I remember her it will be a celebration because that dog has loved me so much, and I have loved her so much, and there is nothing else I would asked for. We lived together, what else can I ask her? Do I want her to be eternally with me? No, she shared what she had, then she was gone, and that's fine, it's the way things should be, what do I want? An eternal relatonship because I can't say goodbye to a friend? Saying goodbye it's also beautiful in it's own way, specially when you have shared with an animal your absolute expression, when you know that there was nothing else for you to be shared, you literally could die and be very thankfull to the dog because you satisfied your soul and shared it completely, you even learnt from the dog.
So be direct, and honest, because important moments are the moments to be that the most, and see what is the right choice, what do you have to do now with your cat. And choose, and do what is best for this life, and for your heart.
I wish you the best and I hope that you remember your cat because, animal friends are the best friends, they are so unconditional, they will support us eternally. Good luck!!
