I should let My3babies respond for herself...but...
As soon as Ellie moved in, My3babies started getting terrible hives all over her body. She then also got sick and started having asthma attacks as well (she doesn't even normally have asthma at all!). She tried bathing Ellie weekly and wiping her down...as well as vaccuming a lot...but it hasn't helped...plus those things take a lot of time.
Also, Ellie's mom seems to not care for her AT all. Almost never pets or plays with her. She won't let Ellie sleep with her either. My3babies needs to minimize contact with Ellie, it's heartbreaking to hear Ellie crying to be let into the bedroom at night...so My3babies gives in and lets Ellie come into the room to sleep with her, Lily, and Gabby and then My3babies wakes up with hives...ITCHY hives. The financial issues are also there.
Further, 3 cats are more work than 2. Which is why I have My3babies' third cat (Kota, Mr. FLUTD) at my house for the duration of the school year, so that she can focus on school and not so much on cat care.
So, I don't really think taking Ellie back is a good idea. Sooner or later Lily is going to have to adjust to life without her...it's just a matter of helping her make that transition.
Any ideas on how?
