Small amount of blood after defecating

[Bogertophis]

How long have you had this snake? I believe she most likely had them already when she came to you. Snakes are stoic & not everyone is an observant keeper- children can easily pass along pinworms to pets or vice versa, & snakes can have worms for a long time if no one is paying any attention or thinks that the minor symptoms are "normal".

By the way, just to be clear, when I said "not everyone is an observant keeper", I wasn't referring to you- I meant whomever you got this snake from.
