Other Senior FurBaby Not so Good. UPDATE
I lost my Siamese blue point/lilac point female (approx 19 yrs old) end of February and now my male Bombay isn't doing so hot. He was put on hyperthyroid meds about 3 months ago which made a world of difference to his symptoms but now has become very lethargic over the past three days. He's approaching 13 yrs old and has had teeth problems (he just had six extractions about two months ago).
He seemed to be missing my older Siamese for a few weeks but then I adopted a Bengal female kitten about 6 mos old and another Blue point/Snowshoe female Siamese who adores him (the feeling is not mutual)
Probably the stress from the Bengal being super active and the new Siamese/Snowshoe didn't help either. Chef has him at the vet's now where they are doing blood work and xrays.
UPDATE: He has a high white cell count but no other symptoms other than lethargy and dehydration. They gave him some fluids and antibiotics. I also have some probiotics to mix in his food. He seems much more alert today.
Thank you for all the well wishes!
