custom cage problem

OK, I'm seeing plywood, lino (linoleum?), and poly varnish (polyurethane?). Anything else?

Plywood--if it's the least expensive construction grade has glues that can outgas for quite awhile.

Linoleum-- "The main ingredient of genuine linoleum is linseed oil. (In Latin, linum is the word for linseed, which comes from the flax plant, and oleum means oil.). The oil is boiled, mixed with melted resins, and combined with powdered cork, wood flour, resins, ground limestone and other natural materials. Mineral pigments provide the color." from Linoleum Frequently Asked Questions

Purportedly linseed oil is nontoxic. However, if the material you used is not genuine linoleum, you might have some toxic materials. Or some of the other materials in linoleum may be toxic.

The varnish--is it completely dry to the touch? If not, it most certainly is still outgassing. However, it can still be outgassing even if it feels dry to the touch.
Or it maybe some other components you used in the build? Can you name all the components you used in the build using full names?

yeah i think its the lino my mum came in and said it was a new lino smell and should go away but its been ages and its still here

[Chu'Wuti]

Do you have the enclosure outdoors (someplace protected from rain) to aid the outgassing?

[phil_7870]

no its inside (i live in ireland for and like the last 3years we got bout 2 weeks of sun ) i have it in a room were there is always traffics so the air keeps moving

Yeah, I know Eire doesn't get lots of sun like some places I could name. Even so, if there's anyplace outside you could set it for a couple of weeks without ruining it, it might help the outgassing. Also, if you could air out the room somehow, you might find that part of the problem is the smell is getting into other things in the room.
