Ok so I’ve had this ball python for about a year now , it’s never really eaten to often, every 2 or maybe 3 weeks since we got him , but it never looks unhealthy , it’s nice and plump , no rigid spine went bent over or anything . It’s temperature is perfect , around 90 on hot , 79-80 and cold side , water , humidity , everything good . Nothing has been different at all in the enclosure ? But for some reason it hasn’t been eating these passed 2 months or even a little longer , and I’m starting to get worried , I’m thinking because it’s winter months ? But every week or two when I try to feed it again , it looks not interested at all or it strikes and never eats or just hisses at it . Very strange why it hasn’t been eating , and it’s been loosing a tiny bit of weight too , it’s back is getting a tad right when bending over now , but not bad . I just need help please ..
