Haha. When it comes to Totoros.. I believe you'll have an explanation for everything bro Chinchillas. Haha.

Adorable stuff if not for the high class suite these little fellas need to stay in, would have bought one long time ago. Hehe

JackLene, you type in such creative manner. *Salute

Reputable vet for Chins I'm not sure, cause I have no chins. But Dr. Yeoh (Tmn Medah), Dr Siva (Animal Clinic), Dr Jenny (Hands & Paws) all treat exotic animals. Personally I always visit Dr Jenny.
Check the vet list for address and number.

6 weeks old so round and fat already? Wahhh..
Erm chin, can post one of your biggest size chin for comparison? Never seen how big can a chin grows. Yours seems to be bigger than those that I've seen in petshops.
