Was My Cat’s Passing Written by Allah?

I woke up this morning and found my beloved cat had left this world. He wasn’t just a pet-he was like my own child. I raised him from a tiny kitten for four beautiful years. I’m having a hard time grieving because I don’t know what took him; it seemed like maybe another animal got to him. My heart feels heavy and tight with sorrow. I’m so sorry I couldn’t keep him safe, and the guilt is overwhelming. Is there something I could have done to save him, or was his time simply decreed to end? And to end so tragically? Was he meant to die so young and full of life? How can I find peace in my mind? I miss him so much, I love him dearly, and I don’t know what to feel, how to cope, or what to do. Inna lillahi wa inna ilayhi raji’un.
