I don't think that letting your birds sleep with you is a good idea. I let Myrtle sleep with me twice and stayed in a recliner one night with Rainbow when they seemed scared of something. On those nights they just would not stay in the usual sleeping places. How My Amazons do not get put in cages. Rainbow has a tiny cage he has claimed to sleep in. Myrtle sleeps on top of my aunts bedroom door. In case of a disaster I can grab Rainbow in a hurry. Myrtle would not be as fast but she has a tendancy to freeze and call me when she is scared. Though my Tiels are free flight in their own room I have a large flight cage in there. They seem to prefer sleeping in it or on it. I believe I could get them all out of the house easily.
I have fallen in love with Bowie! What a sweetheart As for crawling into things , Liseth likes it when I have a blanket across me or wearing a dressing gown. She tunnels through the blanket playing peep po. She likes to run up the sleeves or around and down inside my dressing gown. Not with any other clothing though. She doesn't like tunnels if you make them
Rainbow is a real kid. I buy him a toy and he wants the box. Since Charles is missing a cabinet door in the bathroom, Rainbow moved in. I gave him a box to play in and chew up.
When Myrtle slept with me she slept near my neck and head on my pillow with her beak tucked behind my ear. When Rainbow would not go to bed I slept in a recliner. He slept on my lap.
I don't know what was wrong with them on those nights. If they are smart enough to premeditate what they want to pull on us, they are smart enough to come to me when something is wrong. I don't know if something scared them or if they did not feel good and wanted their human to protect them when they did not feel good. (they can get headaches and belly aches too.
I had a little cat that would sleep in the throw on the couch. He did not fair well. He was so little that we did not see him. He was only a small lump and got dumped many times when someone wanted the throw.
I have a cat (Tiza) that loves to burrow under the sheets in the dogs beds - so far, none of them has laid on top of her but I worry about it all the time!
All our furrys love to sleep in bed and against me. There is always one that lays up against my back. I try to ignore pain to keep going. After all the prednisone I took for so long my back is twisted. Sometimes I do not recognize the pain in my back until a little furry critter gets up against the right spot. I can feel the pain easing up even when I had ignored it all day.
There are pet beds that are designed like an envelope so the pet can get in and under cover in the right place.
Yes, I bought one of them for the min pin I found in the street but she doesn't use it, she gets between my sheets and sleeps cuddled against my back (I have the other 'found' dog stretched out leaning against my front on the other side and the one we adopted from Animal Control on the pillow, against the top of my head).
