Routines and consistent actions allow our companion parrots to know what's coming. That is a double edged sword when it comes to some moments. Travel cages when only offered and utilized for trips to the Vet can lead to the "AHHA! Oh NO I'm not going in there!" If you are like me, and only transport for healthcare, then this is a familiar issue. I bring out travel cages once or twice a month for no other reason than to offer play and adventure. I set them on the couch, the table or a chair and they are filled with foot employment opportunities, blankets and surprising treats. Items only ever offered in their travel cage. I leave them out for a few days and allow every birdy to investigate and enjoy. Then I put them away at night when no birdy is looking.
On Vet visit days I assemble them back, fill them with a few choice items and leave them out. I have volunteers lining up to get going. And yes, our companion parrots are able to put the idea together they have a "chance" of ending up at the vet. BUT, they also know they have a higher "chance" of not. And we all know our companion parrots are about taking calculated chances for a favorite reward. Attaching happy results to otherwise stressful events and items goes a long way, and is a short path to follow.
