it could also be a form of protest..her mums been taken away from her..
it could also be the smell of new baby..like ahving another pet in the house and the girls rooms..territorial!!
Im going through thismess with bertie right now something awful..but he also uses his tray to wee and poo in too..its very odd is territorial as its only in my bedroom where they were holed up when my house got flooded the other week..and in the lounge.marking perimeters of the room i swear!
Hes always done it a bit to bif..but then she did that with oscar then stpped apart from in the overnight cage theyhad..
I agree about your other half helping..also ask friends relaives if theyd babysit inside your house whilst thumper and youhad time togehter?
we spent more time with bertie last night as he appeared in middle of lounge..and got made a right fuss over..got groomed 2 days in a row and got hugged so much (hes a massive french lop so hes more like a dog!) there was no wee when i came downstairs..but when the kitts were loose he did one massive wee by his water bowl..
theres been one accidnet tonight..he peed accidnetally over the edge of the tray
so making a fuss paying more attention may have helped..in my case its hard cos fench lops sleep so much!!
maybe use a litter pan in the rooms she uses to see if it helps..
if this is really too much for you to cope with and will end up making you miserable and resentful then maybe rehoming her is for her best interest..but dont be hasty..you may very much regret it..
im sure you said once before she waspsayed?
the other thing is find her a friend..get someone to bond them for you perhaps and with company of her own to amuse herself with whilst she bombs around she will feel less neglected and love the time you can share with ther and her pal even more
im sorry i cant be of much help..
