Behaviour.

[Nelly&Kip]

I got Nelly and kip in November from pets at home. They where 2 months at the time so around 4 months now. They came to me with ringworm so had early time with me going backwards and forwards to vets and on medicine. They had a few weeks clear over Christmas but now Nellys has returned, just on her nose. Anyway, after vets trip on Saturday they both came home very cranky (think they came into heat on the same day and at the same time- lots of rumble strutting, circling each other and mounting) now Nelly is out of heat she has calmed right down, however kip is still rumble strutting (she always has but this is deeper and more often) and is still occasionally been trying to mount Nelly. They've never been close to the point of sat snuggling but eat next to each other and chase around and play happily. Very concerned this is the start of a falling out. New Guinea pig owner so any advice would be much appreciated.
