Ok, now I am not 100% on this so please anyone correct me if I am wrong... A
dangerous wild animals license I believe is obtained local council offices
but you might want to start your search
here...(www.defra.gov.uk/wildlife-countryside/gwd/wildact.htm)  To obtain
this licence you have to satisfy a MAFF vet that the area in which the
animal is to be housed is suitable and SECURE. Dependant on what you are
going to buy, be it a Raccoon or a Tiger, the accomodation is going to cost
quite alot of money, these guys know what they are looking for and a cage
made out of fence panels and chicken wire is not going to suffice! I do not
have a clue what the fees involved for applying and renewing a lisence
are(believe they are not cheap). You may also run into problems regarding
local byelaws. Eg planning permission, councils may also have byelaws
prohibiting certain animals etc etc.
IMHO getting a gerbil can be testing enough for some people.... (true have
seen it :o)  ) you really need to ask yourself why you want to go down this
road and  try and put yourself off by thinking about all the negatives...
for example an extreme case of the thing getting out and seriously harming
someone... then finding out you are not insured... can you actually get
third party insurance (?) etc etc
I don't keep any animals subject to a DWA lisense but do keep some that at
best can be considered ill tempered, even with these I have to be careful
about my practice as the harming of a person is unacceptable to me... even
if that person is me and are aware of the risks!

Good luck,
Tim

For a cat as a pet you'd be very unlikely to get one but you would require
planning permission ( ?200-300) & then an annual fee ( ?138 from my council)
The enclosure would have to be secure with safety compartments - think zoo!
A normal studhouse is about a thousand pounds but stud boys are allowed to
leave their enclosure & often get neutered & move into the house at a fairly
young age so you'd have to think bigger - think of a 12x10 chatlet with
sofa,TV & central heating with a 12x12 run as a minimum. ( c. ?5,000?)

What about holidays? Catteries are not allowed to take these unless they
have DWAA facilities - I used to but the demand died out.

I've met pet chaussies in the USA - I'd either get a tabby or red British or
leave my details with rescues as willing to adopt a "monster"
