Interdimensional Cats

My cat, Onyx, her amber eyes sparkling in the sun, stared at me lazily. Her black fur, brown striped in the glow, ruffled in a faint breeze.
"How you doing girl?" I ask as I slump beside her. I scratch behind her ears, and a deep purr, rumbling and loud, swells in her throat. I close my eyes, maybe I should just sleep here, here in this peaceful garden, with the sun and the bird and the breeze, fluffy against my cheek. A voice, deep and female, wakes me.
"Hey, Morgan, you gonna feed me or what?" I start, but the garden is empty, just me and the cat. I stare at her, eyes narrowed.
"Morgan, I'm starving down here!", Onyx meowed, irritation creeping into what had to be her voice.
I almost fall of the bench. "You spoke? You can SPEAK!? Why have you never spoken before?"
She looks at me challengingly. "Feed me and I'll tell you". Numbly I get up and stumble inside.
As I pour a bowl of Whiskas, she circles like a shark, prowling around the laundry basket. Onyx rushes over and stuffs her face the moment the bowl touches the ground. Between mouthfuls, she says "This may be a little hard to understand, but this is a pocket dimension."
"A pocket dimension? Like in the movies?" This makes no sense - if this is a pocket dimension, how did I get here? As I ask, she tilts her head.
"Good question. Well, when we, and by we I mean us cats, sleep, we can travel dimensions. Thats why we sleep so much. This time, I decided to bring you. Here, all animals can talk, or rather you understand us. She looks at my blank face. "I told you it was complicated. Use that web thing you talk about so much," she purred. "Or ask your trainer, what do you call them?” I ruffle her fur, my fingers running through the velvet black.
“Teachers. Their called teachers. Anyway, to us, other dimensions are just theories. Is there anything else? I mean, apart from the house and everything." She considers my words. I can almost see her trying to work it out. "Do you actually know?" She shifts uncomfortably. Finally she answers. "I'm not sure. I've never been out of the garden." Her uncertainty scares me. Is this an island, surrounded by an infinite void?
"I'm sending us back now." As she speaks i feel nauseus and the room swims in front of my eyes.
I wake In the garden, the sun now sinking over the horizon, painting the sky with pink and gold hues. Was that real, or a dream? I guess I'll never really know…
