I have a rabbit who lost her cage mate, her daughter. I thought she might be depressed, as she perked up and started to finally eat after I introduced her to a pair of kits--she's very maternal--but she was still only eating wheat, hay, or papaya, none of her usual pellets. I gave her a more in detail checkup today, a few hours from once I noticed she wasn't eating much, and noticed she had mouth ulcers? Look like zits, they're white, on either side of her front teeth. I could take her to the vet, but if there's anything I can do at home, that'd be good. Any idea what would cause that? Tooth infection, maybe? Or abscesses? Thanks in advance for any help! I've lost two rabbits since May and I'd really like to get through this one okay.
