Cage Advise for Dwarf

[JenAndPikachu]

Hi!

I only found out recently that the cage I have for Pikachu is too small and I'm freaking out!
Its a Ferplast Mini Duna.
I've looked at about 1 million cages so far And don't know what to buy!
(Well I've looked at at least 60 cages)

I'm liking the look of the Multy Duna. Very similar to his current cage and much bigger. (Was on Amazon yesterday for £35 in red, this morning has already sold out and its available in blue for £55 now! Annoying)

Still going to look into other cages, so what does bar spacing for a dwarf need to be?

And I know the minimum cage requirement for what the cage needs to be but what would like a recommended cage size be? Because 'minimum' doesn't sound like even that is the ideal size.

I don't have a huge amount of room for a massive cage but I can go much bigger than what he has.

Plus I want to spent about £30-£60, maybe a little more for the perfect cage.

Please Help!
