Many vets will close the incision using dissolvable sutures in an intradermal subcuticular method aka internal stitches. You may feel the end knot or a lump just under the skin but these do not bother most rabbits. This limits their ability to chew them, while still allowing them to groom their own wound, the method is used a lot for cats-particularly feral cats as like rabbits, they are big into grooming themselves
My boy was glue for his nueter and my female had internal stitches and glue for hers.
When he accidentally had an abdominal incision they used external stitches and I cannot fathom why anyone in the world would think it’s a good way to stitch up an animal.
I would say to avoid doing anything that draws attention to the stitches-bandages tshirts, if she struggles she’s more likely to tear them.
For the first day she probably wont feel like grooming, or eating or doing anything other than sitting there bemused.
After that keeping her quiet is really important.
You can get a cone for rabbits, or a collar(it’s like an Elizabethan collar so she cant turn her neck to get at her stitches)
Rabbits will groom themselves. The worry is over grooming the area, so ask your vet to use internal stitches to minimize it.
On the plus side they heal at an incredibly fast rate!
