Thanks for replying!
I got them when they were around 3 to 4 months old so they would have probably already been in puberty, and they were never neutered because every time I made an appointment Bobby would get sick and she was never really well enough. However they still got on fantastically. Also when Bobby died they were both around 10 months old, wouldn’t that be past the puberty stage? And I did actually get them checked by the vet they were both definitely girls.
It never came across my mind that they weren’t bonded at all and just thinking about makes me feel sad, as I thought that they were best friends all along (they sure looked like it).
Thanks for the tips on getting another bun. I have taken all factors into consideration, but I’m still just figuring out if she’s happy enough on her own. And of course I have to get her neutered first.
About her being bored, I have given her toys, loads of chew mats, a diggy box, hidey houses etc. But she never really plays with them, and I don’t have the money to go to the pet store and get all the expensive toys there. I will look for some other DIY toy ideas, but again, she doesn’t seem interested in anything i give her.
