great advice up to this point. I have a 13 week old TAG we pulled out of a pet store at 8 weeks. Few notes from my experience:
1) Don't clip unless you have a dire reason, and then... it's not a good reason. These are prey animals and psychologically need to know they can flee (flight).
2) Don't sweat weaning. Our Cleo is still taking 2-3 handfed meals a day, depends on her mood. Some days she eats it all from the bowl with no help, some days she wants daddy to feed her. I have no problem taking 6 months to wean. The only timeline you need to adhere to is between you and your baby. Read up on abundance weaning... very important.
3) Keep the cage safe and as big as you can. Couple towels on the bottom will be fine.
