Please help.
I have a 8 year old female Bengal, named Smidge. We got her from a Bengal breeding home when she was 7 after she stopped producing more than 1 kitten. She is now desexed. And living with my family with 3 other cats 2 boys 1 girl all desexed.
But lately she has been eating ALOT and trying to escape. Even though we often take her out under close eye to eat grass.
Also she has started meowing at the top of her lungs. Followed by peeing everywhere. She has her own litter box.
What can I do? She comes from a home with lots if cats. And gets along fine with mine. We have had her for 2 years. Yet now this odd behavior has started. Its spring. But she is desexed. Is the peeing a sign of heat? What can I do to stop this odd behavior?

Hmm. you got no reply yet.

Any sudden change of behaviour is a concern imo.
Peeing out of tray could be triggered by territorial stress [enemy kittys in your yard?] and I would be looking to witness this peeing to see if it is bum down squatting pee or a standing spray.
Adding a plus one traay is a new and *safe + quiet* place can benefit also.

But a first step has to be a vet check to rule out medical issues.

good luck, please update us?
