How do I handle repeated pet loss with a very sensitive 3-year-old?

My 3-year-old daughter absolutely loves cats, and unfortunately we’ve had an awful run of losses this year.
In February, we lost our 16-year-old cat. She took that loss very, very hard. A few months later, we got a kitten to be a companion for our resident 4-year-old cat, but that kitten unexpectedly passed away in July, only about three months after we got her. My daughter was devastated again.
Yesterday, our resident 4-year-old cat died unexpectedly as well. My daughter doesn’t know yet. And now, as I’m writing this, my husband is on his way to the emergency vet with a new 4-month-old kitten we brought home only two weeks ago. She has developed some concerning symptoms after being exposed to our other cat.
So potentially, we could be dealing with four cat losses within six months, which just feels unimaginable for a 3-year-old.
My daughter is extremely observant, sensitive, and deeply feeling. She loves her animals intensely, and the first two losses were genuinely very difficult for her. I’m worried about what repeated losses like this could do to her emotionally, and I really don’t want her to develop a fear of getting attached to pets or feel like every animal she loves is going to die.
I know the general advice is to be honest with children about death, and I don’t want to teach her that lying about death is okay. But I’m struggling with where the line is between being truthful and protecting a very young child from more grief than she can reasonably process.
For example, if she asks where the 4-year-old cat is, I don’t want to tell her that she “ran away” or “went to a new home” if that’s not true. But at the same time, I’m wondering whether I need to proactively tell her about the death right now, especially while we’re waiting to see what happens with the kitten at the ER.
Has anyone dealt with multiple pet losses with a young child? How did you handle it? Is it possible to be honest while also protecting a 3-year-old from having to process so much loss at once?
