Draco can't help being turned into animals

"Mutare mate Oryctolagus cuniculus!" The hex hit Harry, but had no physical effect on him, he continued to pursue the dark wizard
"expelliarmus!" (I listened to the audiobooks IDK how to spell shit) The spell Harry cast landed and the dark wizard's wand went flying, making it easy for Harry to catch the dark wizard.  He brought the wizard back to the ministry to put them in wizard jail, and one of the on-site healers stopped him on his way out after dropping off the prisoner.
"Everything alright?"
"Yeah, I was hit with some curse but it didn't work"
Harry returned to his office and sighed as he sat at his desk he leaned back on his chair for a moment and tried to think of something else he could do besides paperwork. He grabbed a quill and began to write. "Suspect was caught purchasing a," he wrote, pausing trying to recall what the object was. He was relieved when an owl flew in through his open window and dropped a letter on his desk. He undid the ribbon around the note and looked at it. It had a hastily written message on it 'Come to St Mungo's Draco needs ur help'
Harry got up and grabbed some floo powder before stepping into the fireplace.

"Mr. Potter your husband is here to see you," one of the nurses told Draco
"No! He is the absolute last person I want seeing me in this state, he cannot come in." Draco says
"Draco, your husband will need to be informed of your condition, he might be able to assist in figuring out what happened"
"I already know what happened, at work, someone probably managed to hit Harry with one of those hexes that only affects the target's mate"
"And Harry won't have any more information about what's going on because he doesn't pay attention! There's no need to involve him in this, just fix me!"
"Draco, you're a healer, you should know that we can't do that without knowing what the curse was"
"How many curses turn someone's mate into a bloody rabbit!"
"A cute, angry little rabbit," Harry says, walking into the hospital room and picking up Draco, gently petting his head. "what happened to him?"
"It's pretty fucking obvious what happened, now what hex did this to me!"
"How would I know? Why was someone casting hexes in the hospital?"
Draco purred involuntarily and nuzzled his head against Harry's hand, calming down as Harry petted him. "You're the one who was hexed. There are plenty of hexes that affect the target's mate rather than the target themself."
"Mutare mate... Something something, I don't know what the other two words were"
"So it was a hex, not a curse, that's good; now, how do we reverse it?" Draco asks
"It should wear off on it's own," one of the healer says "until then I guess you'll just have to wait"
Draco looks up at Harry "this is your fault Potter"
"You're much cuter as a bunny than as a ferret" Harry says.
"You're gonna have to bathe me, and I need my fur double-conditioned" Draco huffs
"Yeah yeah, I'll take care of you dray, what am I supposed to feed him?"
"I am not eating rabbit pellets!" Draco says
"Feed him foods safe for bunnies, I wouldn't risk giving him meat or anything bunnies can't digest"
Harry nods and left with Draco
