Pet Platypus In Uk Can I Have A Pet Platypus In The UK?

Can i have a pet platypus in the UK? - pet platypus in uk

I live in England and asked me if I could have a pet platypus? I know that they are toxic and they need water (like a pond LOL), but Phineas & Ferb (Disney Channel have serial) Perry the Platypus - But I know ITS NOT REAL! = P

I wondered how I could get one, what should be done to have one, how much it would cost and whether it is in the zoo, or a person in the United Kingdom.

Please do not say "OMG you're so stupid Phineas and Ferb is a cartoon, I am fully aware and have asked me whether I could really happen. Thank you:)
