The vet has just been out and given the buns their 6 monthly vaccines. They all behaved very well, even freaky Sorrell, and were given a general check over. The vet says that we should probably remove the mammary lump on Mitzi and send it off because it is still a discrete lump and hasn't spread. She's thinks we shouldn't spay her but keep a check on her and if any problem then spay her.
