Newman is about 4 months old. Throughout the last 24 hours he's been throwing up about every five hours. He isn't drinking or eating and even though he's usually energetic, he's been sitting in the same corner all day aside from getting up to vomit. He did recently chew up one of his old toys. The toy was a fluffy hot pink feather boa-type thing. We thought that it was just upsetting his stomach, but he's chewed on similar toys before and never had a reaction like this. Although the boa was showing up in his vomit before, now there's only a pink liquid. I haven't been able to sleep because I just feel so bad for him. Should I take him in immediately or wait a little longer to see if it gets better? I read to take away his food and water for 12-24 hours and monitor him then slowly introduce a rice and boiled chicken diet. Should I try that or does he need to be drinking water? I'm a little lost and a quite a bit worried. Any words of advice would help!
