Not everything, but pretty close. It all comes down the way their mouth is constructed. There are four teeth at the front that shred just about anything and their chheks 'cave in' so that they don't swallow what they're chewing on.
no they did not bite a rat.
You usually do not have to vaccinate at all after a rat bite.
Streptobacillary rat-bite fever occurs up to 22 days after the initial bite or scratch
They nibble on food, fingers, and almost anything you put in their cage. You can put a wooden block in your rat's cage for them to chew on. Never put you finger in a very fiesty rat's cage or it will bite you and it will hurt. Badly.
No
RAT! plus they have more diseases.
It is unlikely that a rat snake would kill a dog with its bite. Rat snakes are non-venomous and typically only bite as a defensive behavior when threatened. A dog may experience some pain and swelling from a rat snake bite, but it is unlikely to be fatal.
It is not that easy to get ill from rat.In the past Plague was spreaded by rat flea,now the disaese is almost extinct.Few other other diseases can be transmitted by rat bite eg.rabies.But these are rare.Rat bite can produce infection in the wound.Now a days disease called Wiel's disaese(leptospirosis) is spread by rat through contaminated water with rat urine.
yes it can bite
No, they will bite but rat snakes are not venomous and they lack the two fangs seen in venomous species, a bite from any rat snake can be rather painful, as the saliva of the snake may contain bacteria causing an infection that must be treated.
If your rat is acting the same as it always is, then it is normal. If your rat is shaking, having diarhea, biting when it doesn't usually bite, or anything else unusual, then take your rat to the vet. If it is biting more often and being more agressive, then your rat might be pregnant.
Shots of procaine penicillin G or penicillin V by mouth are effective against both streptobacillary and spirillary rat-bite fever
