A few of my rabbits are P@H adoption rabbits.
Athena is great, a lovely rabbit, full of character etc. Got her spayed at their vet - they missed out on a developing abscess post-spay. She had it removed at our own vets and nearly died on the table. 2 years later and she's in fantastic shape.
Rivergrace and Morningstar were adopted as a pair 18 months ago. Both were already spayed to make them more adoptable (usually you get the voucher for the in-house vet). Apparently they were closely bonded and just a bit timid due to being passed from shop-to-shop with no one adopting them. Got them home, they both had extreme fear aggression and their bond fell to pieces within a month. It turned out they actually tolerated each other more than love.
Both girls now live happily in their respective groups. Both are much less fearful but it does still show itself occasionally.
Finally, Iris and Arce six months ago. Iris was sick with a chest infection and I literally had to fight the store to get her treatment as they missed it. Unfortunately by the time she got treatment, it was too late, and she passed away in March. She was also deaf, and underweight which they didn't notice either. Arce was also underweight too and had an historical broken toe which they hadn't noticed until I pointed it out the day I adopted them. Arce is now bonded to her Honeybunny husbun and totally in love with him.
I'd say "once bitten, twice shy" with my experience but apparently, I take longer to learn than most!
