It’s always a good idea to bring a bunny to the vet for a check up when you notice odd behavior. That said, how is she today? The first thing to watch for is her consumption of her regular meals (not treat fruits) and her poos. If she is eating her greens and hay and is regular in her litter pan, it’s less worrisome than if she has refused even more food. (In that case, vet asap.)
Strangely enough, she may be aware that you are in discomfort, and was being sweet to you. Rascal may not have smelled OK to her, or she may have wanted to be alone, or with you, and not in the mood for him then. I don’t usually talk anyone out of a vet visit, because the smallest thing we pick up on is often an indication that it’s warranted, but I am wondering how you both feel today and how the other things I mentioned are as of this morning.
Let us know what you decide to do. (And of course, if she is due for a vet check up, definitely take her anyway.)
