Hi and welcome to YT

.
I went ahead and copy/pasted your question into this thread for you.
When there is a gel like substance in the poo - it's important to note the details like you did; when the gel is at the end of the poo, it usually just means they're emptying some anal gland substances -- whereas if the poo is encased, there is a possible GI issue further up in the small intestine.
