Hi Maiko,
I think I'd take her to the vet, sooner rather than later - only you know what these marks look like and yes, they could be bites from some insect/parasite or they could be a rash which is an allergic reaction to someting in her diet or possibly in her environment (considering the points of her body they are on).
In any event when people get insect bites, particularly multiple ones, or have an allergic reaction is is usually at best VERY uncomfortable and can also be extremely upsetting and painful :( Just try and think how she might be feeling and please make an appointment for her tonight if you can still get one.
Let us know how she gets on,
Good luck,
Teri :)
