I own 2 females and have always lived together since i got them 3 years ago, recently Piggy had to have surgery to remove a sebaceous cyst just under her ear, following the surgery she developed a UTI so was on antibiotics, both of those things really impacted her so she was pretty much not eating and it was very difficult to feed her critical care as she would refuse it and I had to practically force feed her. She then started to put the weight back on and finally 3 weeks after surgery started to eat veg, pellets and hay again on her own and now is always eating her hay. During this time she started eating her cagemate's (Kiwi) poops and the more she ate them the more she bothered Kiwi for them, and it came to a point that she would not leave her alone to eat and would even attempt to get her out of the hidey to look for poops and to make her poop to eat those too, and for the last week or so she didn't just eat the poops on the fleece but would get really close to Kiwi's bum trying to get the poops before they landed on the fleece. I intervened constantly so that she is left alone to eat and rest in peace but it is almost impossible to supervise them 24/7, i also tried separating them a night when i cannot supervise them but they both would go crazy biting at the grids trying to go to the other side that i would just give up and allow them to be together. Anyway I thought her trying to continually eat poops was because of her gut due to being on antibiotics and what she went through so would try to give her poop soup but she would just not have it, i also give her fibreplex but once back on the cage she continues to pester her sister for healthy poops, and today upon close inspection i noticed that Piggy had not just sniffed at Kiwi's bottom but had actually plucked the hairs making the area close to the grease gland area raw. I have now separated them for good until Kiwis bottom heals and Piggy's gut issue resolves, and I wanted some advice on how to treat Kiwi's sore area and on what exactly is making Piggy do this to her.
