erm.. if jumping mean okay wor.. if crawling mean surely got problem liao.. wat have it been eating ? got mites or any injuries on the outside.. pick him up and check check.. weight ok? got loss weight or not?

might be broken...my gp Yui had this before tom, coz at that time i am so stupid and dun cover the cage base so her leg go stuck between the gap between the base bar...She heal on her own.

eating a little as it how much? pellet and hay consumption ok? how is his poo? loose or normal hard?.. the leg problem is both leg or jus one.. if both leg better go c dr. liao.. might not be injury but sickness..

Maybe Vit C Deficiency. Got feed with LC-Vit or not? Or do you feed him with vege with Vit C. When he walk, how he walk? Is it hoping little by little like rabbit?... Last time 1 of my gp sit there only and when want to move forward, she using "hoping" style like rabbit....but still know to eat..... So i put Extra LC-Vit to her drinks, and she began to heal, after heal, i put normal back.

Thank God everybody is ok...you take care ya, may you get well soon~! 
um what brand do you use? if the greenish vit-c drink i dun recommend (forgot the brand) coz in my experience my GPs drink less when i put that solution into their drinking water, plus it stains the bottle so easily. if you want to give vit C i recommend tablet form, all my gp love it, they take it as treats rather than a supplement  well not sure what the other GP lovers would recommend, but i vote for the tablet form.
Which Pet family do you went? I went to PLC bukit tinggi last friday, got a few very good looking shelties and peruvians, and 1 teddy agouti  (i think its teddy coz the coat is short and fuzzy) all @ RM188 each XD

wats the different ? 

Looks like this

This is my new bought piggy from pet safari @ Ikano. i named him Magnum, i call him Mag!! here's the pic. But i think he got mites. After bath many time with shampoo & spray but the condition still the same. so worry leh... by the way what breed is this? the salesperson said its long coat so they sell me more expensive than the others pig...

Pet family (near Giant Bkt tinggi) PLC (Jusco) got sell...

But yeah, i always recommend home breed GPs, they are more well treated and heathier
