I've had excellent service with Martins & Elite Pets.I highly recommend both.
Lisa~ If I went with an aquarium,I would use a screen lid for ventilation.
I love the cages that you can join& add on to with tubes,but continuing to buy those would be costly.
I had my mice in a smaller hamster cage for a bit,but that cage leaked.I had no escapes with that one at all.& I housed them in that cage when they were the size they are now.Full grown& a bit on the beefy side
I wonder if I should ask them to do that modification (Martin's cages I mean) It's super sweet for them to do that if I still chose to go through with getting the topper.(They said they could do a 1/2 x 1/2)
My mice habitat would be housed on a table that they cant get off of.They sometime have "camp outs" on one of my shelves& they don't jump from such heights (I know they could climb if they had access to a table leg) but I'm still thinking,if I go with the aquarium topper,if they get out,they will be on a table
I also used to have mice living (full time) outside of a cage.(When I had lots of mice) & they lived their full life with no escapes or the like. I'm still thinking.
As I said,these mice I have now haven't escaped out of anything yet.
Not saying they never will.I only had problems with baby mice escaping from bars,with the exception of one cage I had that had huge spacing.
It's still a thought...
This is the one I was looking at: 10 gallon aquarium topper
I would cover the wire somehow though.In my rat cage I have carpet.I like my critters having something solid to walk on.
May use carpet for the mice too.But my rats are litter trained,mice aren't,so that might not be so good on my nose
We'll have to see.
