Hi, I am building a table for my 3-toed. Going to use polyurethane to seal the wood. How long after the last coat (3 or 4) should I wait for it to cure before using the table?

I actually work for a Polyurethane Manufacturer.
There are tons of various types of polyurethane. If you can let us know the brand and type of polyurethane/polyurea you areusing.. I can tell you how long the curing process takes.
Is this Urethane a 100% solids urethane or is it solvent based.
Id shy away from solvent based if possible. They typically can take 5 - 7 days for the solvent to leech out. Depending on the kind of wood your using it can also trap solvent for longer. Temperature plays a big roll in this.
If you can keep the coated wood in the sun or a warm place the solvent will flash off much better then at standard room temp.
To be safe for an animal housing Id suggest 3 to 4x longer then the manufacture states as its functional cure time.
I coated my new enclosure which i just finished last night, with 100% solids polyurethane. Tack free cure time is under 15 minutes and functional cure time is 12 hours at room temp. Food contact grade to be safe for the animal.
I will post pictures soon.
