<human>: Condense the text into a few key points

My sister was always a huge cat lover. When she died, she didn't have much. But she left me her 4 year old Siamese cat, Lollypop. I have bonded with this cat so much. The first few months we were both inconsolible and this cat was the only reason I didn't fall off the edge of the world or go back to drinking (3 years sober.) 

Lolly is obsessed with me. She sleeps with me. I have another cat, Toast, and they are best friends. The problem is, my boyfriend and Lolly do not get along. Mark is a dog lover and does not like Lolly sleeping with us. He 'tolerates it' because I cannot sleep without her. When I am on a trip somewhere, I have to have to play a recording of waves because Lolly sounds like an ocean when she sleeps with me. 

I guess the problem is, Mark is the first guy who I have dated who didn't love my cat(s). Every other guy I had loves that we have animals in the bed. 

I can't get rid of Lolly. She is my best source of comfort. I guess this makes me weird to people like Mark. But I just don't know how this will end well. I will be giving up a stable guy for a cat. But the cat belonged to my best friend and best sibling. 

I loved Jana. Lolly is the last thing she loved in the world and she left Lolly to me to take care of. Lolly had atleast a decade left of life and I just do not see myself getting rid of her. I have a good job, I have savings, I have a nice place. I do not want to get rid of Lolly or Toast. 

The thing is, Mark doesn't hate Toast. He just wants Lolly gone. 

I am not sure how to handle this? Is there a way to have the best of both worlds?
