We’ve been fostering this cat for a few weeks and she’d been great until this morning. This morning she freaked out and bit and clawed my leg. Now she’s still growling hissing and crying and periodically stalking my husband and I. 

We’re not sure if she’s 100% blind or just extremely low vision. She’s been blind for most if not all of her life and is about 1.5-2 years old. 

In her previous fostering situation she was bad around other cats but not otherwise an issue. 

We started her off in an enclosure like we do with all our fosters then gave her free range of our  living room bathroom and kitchen in our small apartment. We’ve been fostering her for a few weeks. She got comfy pretty quickly and would sit on the sofa next to us and let us pet her. She was even good with new people. She would occasionally get a bit territorial while sitting in a specific chair but that would be normal flinching or a claws in swat not anything this aggressive. 

She’s had a couple incidents of scarf and barf throwing up with us but no other medical issues. She also fell off the windowsill when she missed a jump but only fell like a foot and seemed fine. 

She was also panting a little this morning but that has stopped. Her pee and poop seem normal. 

She’s also very food motivated (less so today than usual). 

We think she might have been set off earlier because we put a Bluetooth speaker playing a podcast on the floor (we usually put it on a table and it doesn’t bother her there). 

She’s supposed to get adopted on Thursday and right now she’s barely ok being in the same room as people. 

The more experienced fosters at our organization don’t seem to think the vet would help and are just telling us to give her space (which we have been doing). But we literally can’t eat leave our apartment or use the bathroom without being in the room she’s in. 

I’m really not sure what to do please help!
