My male loves the outdoors and I usually don't see him most of the day. He may stop in to see if anything is going on and leave again. Sometimes he is out late at night which I hate. The past few days he stays in the house a lot more and sleeps - under the blanket bed I made him on the sofa. He likes to hide. Now he is sleeping on the chair outside. Maybe he slept most if the day outside and I never knew it. Now I am wondering if something is wrong but I don't have the funds to run to the vet. He is eating normally. Am I just stupid for worrying?
