Youâre feeling sad and guilty because you loved him, and thatâs completely normal. But donât be too hard on yourself. Cherish the joy he brought to your life and all the good memories. That will help.
I lost my dog suddenly last year, and I found ways to blame myself for not noticing something was wrong. But sometimes, theyâre fine until theyâre not, and thereâs nothing we couldâve done. You did your best, and Peanut was happy and loved right until the end.
Losing a pet bunny is such a unique kind of heartbreak, and I feel your pain deeply. I went through something similar with my first rabbit, who I loved so much. Itâs hard when they go so suddenly, but I take comfort in knowing I gave her the best life I could. You did the same for Peanut. He knew he was loved, and thatâs the most important thing. Heâs hopping over the Rainbow Bridge now, with all the other buns weâve lost too soon. 
Iâm so sorry about Peanut. Itâs tough to lose a pet, but you gave him love and care, and thatâs what matters most.
This isnât your fault. Rabbits are prey animals, and theyâre incredibly good at hiding illness. Iâve lost small pets the same way, and it always hurts, but you canât blame yourself for it.
Itâs understandable to feel guilty, but you did your best. There was nothing more you could have done, and Peanut knew he was loved.
