Since the title is so ambiguous, it could be about various things. It might be a fable where the mammal and the reptile have a difficult relationship that brings pain. For example, the mammal could be a small rodent and the reptile a snake. The snake might be trying to hunt the rodent, which is a painful and scary situation for the rodent. And for the snake, if it fails to catch its prey, it could also be in a difficult situation, perhaps facing starvation. So this could be a story about the hardships and pain in the relationship between two different types of animals.
The first step is to take your cat to the vet. They'll prescribe the right medication, which might include topical creams or oral drugs. Also, keep your cat's living area clean.
I found a novel with a cat as the main character. This novel was called " My Years as a Cat [Quick Wear]". It told the story of a protagonist named Lion Cat, who became an honorable shadow guard in the palace in pursuit of wealth and honor. Other than that, there were other feline love novels such as Atypical Redemption and Survival in the Animal World. These novels all had cats as the main characters. The plots were compact and full of sweet love and redemption. I hope these recommendations will meet your needs.
One great Tony Dinozzo feline fanfiction is 'Tony and the Kitten'. In it, Tony finds a stray kitten near the office and decides to take it in. It shows his softer side as he takes care of the little feline. It's a heart - warming story that really captures his character well.
Family can also be a theme. Some stories explore the relationship between a female feline and her kittens, or her family members. It could be about protecting the family or finding her lost family.
A possible plot could be that the mammal accidentally enters the reptile's territory. The reptile, feeling threatened, attacks the mammal. This causes pain to the mammal. Then, the mammal's family comes to its rescue and in the chaos, the reptile also gets injured. So both experience pain.
