Do they have to go to to vet?
Do rats have to go to the vet and if they do how often,my rat is about 6 weeks old.
I wouldn't take them unless I saw some unusual symptoms. Rats really don't need a physical check up unless they stop eating or drinking.
I say rats should go to the vet every few months. They've very prone to getting cancer, and they also don't live too long so they age much faster than you'd think.
I wouldn't take them unless they started to act strange. Like not being their usual normal selfs.
I sure would take it!! Especially since the young boy I believe in california just died from getting 'rat bite fever' from his new pet rat that he & his parents bought at 'Petco'...its just better to be safe than sorry ;-) good luck!!
Some people say once a year for a check up or of you see they are acting not like there selves or look sick
