I have a 13 year old male, neutered, indoor cat. I adopted him from a rescue at 2 months old. Since my son (18 months old), has been sleeping his nights (for the last 7 months), my cat now does a high pitched meow several times a night, waking everyone up in the house. I took him to the vet and he has had blood work done, with everything coming back normal. He usually sleeps in bed with my husband and I, and always has access to food and the litter box as we leave our bedroom door open so he can come and go as he pleases. I have tried ignoring him but it doesn’t seem to work and then I have to go console my hysterical baby who is now very sleep deprived. I have tried putting him in another room but his meowing is so loud that you can still hear him from 2 floors down. Besides the night meowing, he seems to get along well with my son and has not had any other behavioral issues. I can’t take it anymore, any help would be appreciated.
