Supervision, reward and punishment

Honorable Rabbi Michael Avraham Shlita
I have not found a satisfactory explanation for the fact that animals endure real suffering even through no fault of their own.
Although the Torah is quoted in the Jerusalemite name, it seems that there is a connection between the sorrow and the bad deed they did, but this does not resolve the many cases in which, without any fault on the part of the animals, they are devoured with great pain on their part, and as we see in reality, and as Maimonides also writes in the Morah, the animals feel their sorrow and are aware of it.
To shift the blame onto humans for their sin is unacceptable, since the purpose of goodness to benefit requires that it be impossible for a creature to harm another creature without causing it to suffer.
As is known, the Rishonim insisted that there is an unresolved question of a righteous person and a wicked person, and the Ramban, in his commentary on Job and in several places, wrote to imply that this pertains to the matter of reincarnation, which cannot and should not be interpreted in relation to animals that were imprinted with a cruel nature, and whose creation requires that others in the food chain be devoured and suffer great suffering as a result.
The question has been bothering me for a long time, and I would be grateful if the editor could clarify my opinion on the matter.
