Hello, & thanks for contacting Petco Pet Education Center, formerly Petcoach. I am so sorry for your worries with Oscar. The combination of a lack of appetite & a change in behavior makes me wonder if Oscar is some pain. This can be due to an infection, a blockage from an ingested object, a twist in his gut, or any number of possible serious scenarios. You should try 7 get an appointment with your veterinarian as soon as possible. Other than offering Oscar a bland diet ( plain chicken, white rice, low fat cottage cheese ), there is really no at home remedies I can safely recommend at this time without being able to examine Oscar. I hope he is feeling better soon. Take care.
