The door to Calamity's lab opened, and the grey coyote lead the toons inside. At the opposite wall lies a large device that looks like a big container made of polycarbonate, with a bunch of small van-de-graff generators on top.
There are several wires that connects the device to a console stationed a few feet away.
"Wow!", Babs exclaimed. "This thing looks so cool!"
"Thank you, Babs", Calamity replied. "I just finished building it today."
Cliff asked, "How long did it take for you to build it?"
"About a week & a half."
"So, what does it do?", questioned Buster.
"Basically, this machine is programmed to transform any toons into any different kind of animal in any form."
"Really?"
"Mm-hmm. Amphibians, reptiles, mammals, fish, insects, you name it."
Shirley then asked, "Like, can you also change us into mythical animals or some junk? Like a unicorn?"
"Or a fire-breathing dragon?", Cliff said.
"Sorry", Calamity responded, "I can only do real-life animals."
"Bummer", Cliff commented.
"But anyway, I thought it would be something fun to do, so I thought, 'why not show it to everyone else'. What do you guys think?"
"It sounds ingenious, Calamity", Buster said. "Then again, everything you've made is ingenious."
"Well, that's kind of debatable, considering that most of my stuff fails when it come to going after an annoying roadrunner." Calamity glared over at Little Beeper, who waved at him with a smile.
Fifi then raised her hand. "Excuse moi, Calamity."
"Yes, Fifi?"
"Does eet hurt when vous are in zhe machine?"
"Only a leetle", Cosette answered. "Vous may feel a beet of a shock, but eet's not too bad."
"Why do you ask?", Calamity said to Fifi. "Are you thinking about trying out my device?"
Fifi thought for a moment before she spoke, "I dunno. I can't seem to make up my mind."
Furrball turned to his girlfriend & asked, "What are you planning on doing?"
"I don't want to say."
"Why not?"
"Because, I want to keep eet a surprise."
Furrball smiled slyly. "You want to become a cat, don't you?"
"Oui, I do."
Furrball chuckled & said, "It's not really a surprise, sweetheart. I mean, why else would you want to try out that machine?"
"You're right. But, I can't decide whether or not I want to turn myself into a cat. What do vous say, Furrball?"
"It's up to you, my love. If you want to be a cat, I won't stop you."
Fifi thought long & hard about her decision. She wanted to change herself into a cat & see how Furrball would react. But she's not sure if Furrball would love to see her as the same species as him or prefer she stays the way she currently is.
"Fifi", Calamity spoke up, Fifi turning to him, "don't worry about becoming a cat. I can always change you back whenever you wish to do so."
The purple skunk took Calamity's words into consideration. After a couple more moments of thinking, Fifi finally made up her mind.
"All right, I'm doeeng eet."
As soon as Fifi said that, some of the toons, including Furrball, were struck with dread. He is half curious to see how Fifi would look as a cat, but at the same time, he's worried about her getting hurt.
Fifi went up to the machine & stepped inside, before Calamity pressed a button on the console to close the door, completely concealing Fifi inside the see-through device.
The grey coyote used the console to change the settings to "CAT", then slowly pulled a lever to power up the contraption, which emitted a few electrical discharges from the van-de-graff generators.
Fifi placed her hands on the door & looked out at Furrball, who looked back in concern, as the whole container filled with smoke. A mechanical hum grew louder as more electrical discharges shot from the machine.
The toons looked on as the container holding Fifi lit up in a bright flash, accompanied with an audible ZAP! The container lit up a few more times, as Fifi is heard exclaiming in pain from inside the device.
"Ouch!", Fifi is heard shrieking. "Ow! Me-OW!"
The toons all grew concerned, especially Furrball, who's really tempted to shout at Calamity to turn the machine off & let Fifi out.
But, before he even had a chance to do so, the machine started powering down until it completely deactivated. The door then opened, allowing the smoke to exit the container.
The toons looked on as Fifi is heard coughing & gasping for air.
"Le hack!", she exclaimed. "Le gasp! Le cough!"
From out of the smoke, Fifi's hands appeared & grabbed onto the doorway of the machine, as she pulled herself forward & stepped out.
The toons all quietly gasped as she came into view. Fifi looked up & saw the dozens of wide open eyes staring at her.
"What?", she asked. "What eez eet?"
She turned to Calamity, who looked just as surprised as the others.
"See for yourself", Calamity held his arms out to a mirror on the wall. Fifi went up to it & gasped at the sight of her reflection.
She saw that her ears are big & triangular, and her hands are now white. She looked down & saw that her feet are also white. Then she looked behind her & saw the most noticeable difference.
The white stripe on her back is not there anymore. In fact, there is only white on the tip of her tail, which is now thin & curvy instead of large & fluffy.
"Meow", Fifi said in an impressed voice as she wagged her new tail. The other toons continued to look on in astonishment.
"She's beautiful", Babs commented.
"Like, totally", Shirley agreed. Fifi then turned to Furrball, who looked at his girlfriend with a face of wondrous joy.
"How do I look, mon amore?", she asked. Furrball stared at his girl for a moment longer before he responded.
"Well, if I were you, I'd say...ooh la la."
Fifi giggled upon hearing Furrball's response, as the rest of the toons continued to admire Fifi's new appearance.

Later that night, Furrball opened the door to Fifi's Cadillac home for his girlfriend, and the two stepped inside. All throughout the day, Fifi & Cosette were getting compliments left & right about their new looks, and Fifi, despite the pain from Calamity's machine, felt that it was totally worth it.
"Man, what a day it has been", Furrball said. "Everyone won't stop talking about your new look."
"Oui", Fifi agreed, "I can see why."
"I'm pretty sure people will be talking about you & Cosette for days. You might even appear in the school newspapers."
Fifi giggled, "Zhat would be cool. After all zhe comments & attention I got, I'm really liking zhis."
"I'm glad you are."
"However, there eez one person zhat I deed not get a compliment from."
"Who would that be?"
"You."
"Me?"
"Oui, I haven't heard vous say anything about moi yet."
"Oh. I...guess I was left speechless over your new look."
"Zhat eez, how you say, understandable. So, Furrball...", Fifi did a pose in front of her boyfriend. "How do I look?"
"Uhh...", Furrball started. He has a million different adjectives going through his mind right now, it was hard for him to pick one to describe the new Fifi.
"You look so...so..."
"Yes?"
After a moment of hesitation, Furrball blurted out the one word that popped in his mind the most.
"Perfect."
"Oh?"
"I-I mean...uh..."
"Vous think I look perfect like zhis?"
"Y-yeah, you do! I mean, I always thought you were perfect before, but now you proved me wrong."
Fifi blushed at Furrball's comment, which made him blush as well.
"Merci, mon amore."
"You're welcome."
"Zhat might be zhe best compliment I received so far."
"Really?"
"Oui, of course. I expected to hear zhe best compliment from vous."
Fifi gave Furrball a subtle wink, which made him blush even harder. Fifi then went up to Furrball & wrapped her arms around him.
"I'm glad vous like my new look."
"Actually, I don't like it."
"You don't?", Fifi made a face of concern.
"No. I love it."
Fifi smiled at what Furrball just said. Furrball wrapped his arms around his sweetheart & smiled back.
"Furrball?"
"Hmm?"
"How do vous purr?"
"Use the muscles in your neck, to press the larynx against your glottis."
"What's zhe glottis?"
"It's the opening between the vocal folds. You purr by changing the movements of your glottis."
After a few attempts, Fifi is able to start purring with no trouble.
"There you go, you got it!", Furrball exclaimed excitedly.
Fifi smiled as she continued purring. She pressed her head against Furrball's, who also started purring. They looked into each other's eyes romantically, before they closed their eyes for a kiss.
The two cats held each other as they continued smooching lovingly, both purring loudly & boldly. Fifi tried to wrap her tail around each other like she usually does, but she could only hold Furrball's back with her tail, due to how short it is.
As the two felines continued their romance, Furrball, while still hugging & kissing Fifi, wrapped his tail around Fifi's. Their tails are now coiled around each other like two furry snakes, as Furrball kept purring & kissing his girlfriend, feeling very happy that she's now a cat just like him.
