R133 · Three friends, three pets

Given the information:

1. Ana is allergic to animal fur, so she cannot own the cat or the dog; therefore, Ana must own the parrot.
2. Ben's pet cannot fly, so Ben cannot own the parrot; since Ana owns the parrot, Ben must own either the cat or the dog.
3. The dog's owner is older than Ben, implying that Cleo, being neither younger than Ben and not owning the dog,
4. Therefore, Cleo must be the one who owns the dog.

So, the pet ownerships are:
- Ana owns the parrot
- Ben owns the cat
- Cleo owns the dog

Ana owns the parrot because her allergy makes owning a furry animal impossible. Since Ben’s pet cannot fly and he doesn't own the dog, Ben must own the cat. This leaves Cleo to own the dog, which is consistent with the clue that the dog owner is older than Ben. Therefore, Ana has the parrot, Ben has the cat, and Cleo has the dog.

Ana owns the parrot because her allergy to fur suggests she avoids the cat and dog. Since Ben's pet cannot fly, he does not own the parrot; combined with the fact that the dog's owner is older than him, Ben must own the cat. This leaves Cleo to own the dog, fulfilling the condition that the dog's owner (Cleo) is older than Ben. Therefore, Ana has the parrot, Ben has the cat, and Cleo has the dog.

Ana owns the parrot (since she is allergic to fur, ruling out cats and dogs). Ben has a cat (as parrots can fly and dogs are owned by someone older than Ben). Cleo owns the dog, making her older than Ben. This satisfies all constraints. 

**Answer:** Ana owns the parrot, Ben owns the cat, and Cleo owns the dog.

Ana owns the parrot because she is allergic to fur, ruling out cats and dogs. Ben cannot have a flying pet, so he must own the cat. Therefore, Cleo owns the dog, satisfying all given conditions.

**Answer:**

- Ana owns the parrot.
- Ben owns the cat.
- Cleo owns the dog.

Ana owns the parrot because she is allergic to fur, and parrots have feathers. Since the dog's owner is older than Ben, Ben cannot be the dog's owner, meaning he must own the cat. This leaves Cleo as the owner of the dog.

Ana owns the parrot because her allergy prevents her from owning the dog or cat due to animal fur. Ben cannot own the dog, as its owner must be older than him, leaving him with the cat since his pet cannot fly. This means Cleo must own the remaining pet, the dog. Therefore, Ana has the parrot, Ben has the cat, and Cleo has the dog.

Let's break down the information:

* Ana is allergic to animal fur, so she must own a parrot (since cats and dogs have fur).
* Ben's pet cannot fly, so he must own either a cat or a dog.
* The dog's owner is older than Ben, which means Cleo (who is presumably older than Ben) owns the dog.

Putting it all together: Ana owns the parrot, Ben owns the cat, and Cleo owns the dog.

Ana has the Parrot as she is allergic to fur; Ben owns the Dog since it can't fly, and Cleo must have a Cat due to being the oldest among them. This conclusion was drawn based on given hints that helped us rule out other possibilities for each person's pet ownership.

Ana cannot have a cat or dog (due to fur allergies), so she must own the parrot. Ben's pet cannot fly, so he has the cat. The dog’s owner (Cleo) must be older than Ben, leaving Cleo with the dog. Final assignment: Ana (parrot), Ben (cat), Cleo (dog).

Ana owns the parrot because she is allergic to fur, eliminating the cat and dog as options for her.

Ben cannot have a pet that flies, so he must own the cat (since Ana has the parrot), leaving Cleo with the dog.

Additionally, since the dog's owner is older than Ben, Cleo must be older than Ben. 

**Answer:** Ana owns the parrot, Ben owns the cat, and Cleo owns the dog.
