I am really sorry for your loss, I know how hard it is to lose a beloved pet.
As somebody else has mentioned, do Lord Anubis ritual to guide your pets soul, but also, do a ritual to Lady Bastet so she can watch over your pet and if possible, reincarnate their soul so you can have them back in your life if it is what you need.
Sometimes, the same cat doesn't return to you, but instead, another cat comes into your life to help you heal from the grief you feel and learn to love another animal.
I've had an older cat come into my life for a few days and he tremendously helped me finally move and heal from the grief I've been carrying with myself for 13 years over losing my heart cat due to the monsters I've been living with taking her away and her 2 precious kittens and dumping them who knows where..
I still miss her, but I am now more willing to accept another cat into my life without feeling a blockage in my soul and it feels healing!
For now, meditate and focus on the Gods, take your time to grieve, but don't let that grief consume you, it is natural to feel what you do, but just please don't let it consume you and drive you away from the Gods, they're here for us!
Now please stay safe, have loved ones in your life, allow the Gods to enter your life, don't push them away and take your time with things. You will heal from this.
